LT1114IN - 4-Channel Precision Op Amp | Analog Devices
LT1114IN

LT1114IN - 4-Channel Precision Op Amp | Analog Devices

Analog Devices LT1114IN is a four-channel, general-purpose precision operational amplifier designed for low-power signal conditioning and instrumentation applications. The device provides a 750 kHz gain-bandwidth product, 0.3 V/µs slew rate, picoamp-class input bias characteristics, and an industrial-grade temperature range. It is packaged in a 14-pin DIP through-hole package. An operational amplifier is an active analog circuit element used to amplify voltage differences between its differential inputs. The LT1114IN belongs to the precision amplifier hierarchy: precision op amp, operational amplifier, analog signal-conditioning IC, and power-management semiconductor. Its four channels allow compact implementations of filtering, buffering, instrumentation, and active gain stages without requiring four separate single-channel packages. The key performance characteristics include a 750 kHz gain-bandwidth product, 0.3 V/µs slew rate, 60 µV maximum offset voltage for prime grades, 0.5 µV/°C maximum input-bias drift, and low-power operation. These specifications make the LT1114IN suitable for transducers, sensor interfaces, analog measurement systems, and general-purpose signal paths where offset stability and low input current are important. The LT1114IN uses a bipolar precision operational-amplifier architecture. The 14-DIP (0.300 inch, 7.62 mm) package provides through-hole lead spacing for conventional PCB assembly, prototypes, and repair work. Because each amplifier has its own differential input and output pins, the package supports four independent analog channels while retaining a straightforward DIP footprint. Typical uses include low-frequency instrumentation, current-loop and voltage-signal conditioning, buffered sensor interfaces, active filters, sample-and-hold stages, and industrial control modules. The 750 kHz bandwidth is suitable for moderate-speed signal conditioning rather than high-frequency video or RF amplification. Designers should verify supply voltage, output swing, input common-mode range, noise, and stability requirements against the manufacturer datasheet for the exact grade. Decoupling capacitors should be placed close to the supply pins, and unused amplifier channels should be configured according to the manufacturer’s recommended practice rather than left floating. This product page combines the official Analog Devices product information, package and performance details, sourcing guidance, drop-in alternatives, and practical design notes. It helps engineers compare the LT1114IN with pin-compatible options while planning temperature-grade, package, and lifecycle requirements.

LT1114IS

LT1114IS - 4-Channel 750kHz Precision Op Amp | Analog Devices

Analog Devices LT1114IS is a four-channel precision operational amplifier with a 750 kHz gain-bandwidth product, 0.3 V/µs slew rate, and picoamp-class input bias characteristics. The device is packaged in a narrow 16-pin SOIC and is intended for general-purpose precision signal conditioning where four amplifiers must fit on a compact PCB footprint. An operational amplifier, or op amp, is a differential voltage-controlled amplifier with high input impedance and open-loop gain. Its feedback network determines the completed function, allowing one device to perform inverting, non-inverting, summing, filtering, buffering, and gain-control operations. The LT1114 belongs to the operational amplifier hierarchy within analog ICs, combining four precision amplifier channels into one package for instrumentation, sensor, industrial-control, and low-frequency analog systems. The LT1114 family emphasizes low power, precision, and picoamp input bias current. Its 750 kHz gain-bandwidth product is suitable for moderate-frequency closed-loop amplification, while the 0.3 V/µs slew rate provides adequate response for common low-speed control and measurement signals. The prime-grade maximum offset voltage is 60 µV, supporting accurate DC operation when resistor matching and bias-current compensation are also managed carefully. The four amplifier channels share a common package but provide independent signal paths. This arrangement reduces component count and simplifies routing in designs requiring several matched functional stages, such as instrumentation amplifiers, active filters, motor-control loops, and sensor-conditioning circuits. The narrow SOIC-16 footprint is considerably smaller than a wide-body competitor package, helping conserve board area without requiring a specialized land pattern. Typical applications include low-level sensor amplification, current-loop measurement, buffer stages for analog-to-digital converters, active filtering, process-control signals, and general instrumentation. Because the gain-bandwidth product is 750 kHz, the device is best matched to low- and moderate-bandwidth signals rather than high-speed waveform, video, or RF chains. Design with the input common-mode range, output swing, supply voltage, noise, and stability requirements in mind. Place each decoupling capacitor close to its supply pins, avoid long high-impedance input traces where possible, and check the recommended feedback-network values in the manufacturer datasheet. The LT1114IS is supplied in tube packaging for the identified ordering configuration. This product record combines the manufacturer family description, ordering information, package details, and verified distributor metadata with practical guidance on amplifier selection, signal conditioning, and drop-in replacement evaluation.

LT1114S

LT1114S - Quad Low Power Precision Op Amp | Analog Devices

The Analog Devices LT1114S is a quad low-power precision operational amplifier that combines picoampere-level input bias current with low offset voltage in a 16-pin SOIC package. The device delivers a 750 kHz gain-bandwidth product and a 0.27 V/µs slew rate while drawing minimal quiescent current per amplifier, suiting it to battery-powered precision signal chains. A precision op amp is a linear integrated circuit that amplifies low-level analog signals with high accuracy, characterized by low input offset voltage, low input bias current, low noise, and high open-loop gain. The LT1114S belongs to the operational amplifier family within the amplifier IC hierarchy, which falls under the broader category of analog signal conditioning ICs in mixed-signal semiconductor design. Quad packages integrate four independent op amps for channel-dense applications such as multi-sensor signal conditioning, instrumentation front-ends, and active filter banks. The LT1114S achieves 60 µV maximum offset voltage on the prime grade and 75 µV on the low-cost grade, with picoampere input bias current and low supply current per amplifier. It operates from ±1 V to ±20 V supplies, has a 750 kHz gain-bandwidth product, and 0.27 V/µs slew rate. The device includes industry-standard pinout in the SOIC-16 (S16) package, enabling direct drop-in upgrades of legacy quad precision op amps such as the OP-400, OP-497, and AD704. The LT1114S uses a bipolar input stage with bias-current cancellation that delivers picoampere input bias current without the noise penalty of CMOS JFET inputs. Its trimmed input stage and on-chip temperature compensation keep offset voltage low across the -40 °C to +85 °C industrial temperature range, supporting precision measurement systems that must hold calibration over thermal cycling. Typical applications include precision instrumentation amplifiers, strain-gauge and thermocouple signal conditioning, multi-channel data-acquisition front-ends, medical instrumentation, and active analog filters. The wide supply range also supports ±15 V industrial systems. When designing with the LT1114S, choose the prime grade when offset voltage and drift directly impact system accuracy; choose the low-cost grade when budget dominates and 75 µV offset is acceptable. The LT1114S is pin-compatible with the OP-400, OP-497, and AD704 quads, allowing board-level upgrades with no PCB rework. This page synthesizes distributor pricing, drop-in upgrade alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers select and source the LT1114S for precision analog designs.

LT111A - 250ns Voltage Comparator | Analog Devices
LT111A

LT111A - 250ns Voltage Comparator | Analog Devices

The Analog Devices LT111A is a general-purpose voltage comparator with 1.0 mV maximum input offset voltage, 5.0 nA maximum input offset current, and a maximum response time of 250 ns. It operates from a single 5 V supply through ±15 V supplies and is available in the verified TO-5 package. A voltage comparator is an integrated circuit that determines whether an input voltage is above or below a reference level, producing a logic output suitable for control, monitoring, or switching decisions. The LT111A belongs to the comparator family within analog integrated circuits and power-management control systems. Unlike an operational amplifier intended primarily for linear amplification, the comparator is optimized for fast, saturated output transitions and threshold decisions. The LT111A improves on the LM111 general-purpose comparator according to the manufacturer datasheet. Its headline specifications include 1.0 mV maximum input offset voltage, 5.0 nA maximum input offset current, and 250 ns maximum response time. The input stage accepts differential input signals up to ±30 V, while the output can drive loads up to 50 mA referenced to ground or either supply, as stated in the datasheet search data. The component includes offset balancing and strobe capability. A separate output ground pin allows the output reference to be selected independently of the circuit ground, which is useful when interfacing to systems with different output-return requirements. The output can also be combined for OR-style logic, although exact implementation depends on the surrounding circuit and output configuration. Typical uses include precision threshold detection, sensor signal conditioning, window comparison, overvoltage indication, zero-crossing detection, and industrial control systems. The 250 ns response is suitable for systems that need faster decisions than general-purpose slow comparators while retaining wide input-voltage capability. Designers must account for the obsolete lifecycle status, supply arrangement, input common-mode limits, output polarity, and thermal constraints. The verified manufacturer result identifies LT111A as obsolete and directs users to contact Analog Devices for a replacement product. New designs should therefore confirm availability, lifecycle status, and any recommended replacement before committing to production. This page consolidates the verified manufacturer specifications, obsolete-status notice, package information, design guidance, and sourcing limitations for engineers comparing the LT111A with legacy comparator systems.

LT111AH Military Voltage Comparator | Analog Devices
LT111AH

LT111AH Military Voltage Comparator | Analog Devices

The Analog Devices LT111AH is a military-grade, single voltage comparator supplied in an 8-terminal round TO-5 package. It compares one input voltage level with another and provides a logic-level output suitable for threshold, window, zero-crossing, and sensing functions. The verified product data identifies it as an IC voltage comparator, specifies an 8-wire terminal configuration, and states a maximum operating temperature of 125°C. Exact input common-mode limits, output-current capability, propagation delay, and offset parameters are not present in the supplied records. A voltage comparator is an analog integrated circuit that compares two input voltages and changes its output when the difference crosses a defined threshold. Within the broader semiconductor hierarchy, a comparator belongs to the linear IC family and the amplifier IC category. Unlike a general-purpose operational amplifier, its principal purpose is fast, deliberate state transition according to the polarity of its differential input rather than linear amplification. The LT111AH is associated with the LT111 comparator family and is offered in a military temperature grade. The H suffix distinguishes this ordering code from other package, temperature, or accuracy variants, but the supplied excerpts do not expose the underlying ordering-code table needed to state every suffix characteristic. Its TO-5 construction uses wire-form leads and suits legacy or ruggedized assemblies where a through-hole metal package is preferred. The round package also requires care during insertion because lead orientation determines correct comparison-input and output connections. Verified distributor records classify the part as a comparator and show commercial listings through DigiKey, Octopart, Xecor, and other suppliers. The available Cytech Systems result reports zero stock and $0.0000 reference prices, so those values cannot be interpreted as a usable quotation. The Linear Technology page indexed by linear-electronic.com reports 3,320 pieces in stock, but that vendor record is not treated as an authoritative global stock figure. Pricing and availability should therefore be confirmed at order time. The LT111AH can be evaluated for industrial control, instrumentation, alarm detection, and legacy equipment, provided the system supply stays within the family limits. External resistors and protection networks may be needed to constrain inputs or accelerate an open-collector output, but exact values cannot be selected responsibly without verified input thresholds, output architecture, supply range, and timing specifications. This page combines the verified source excerpts with explicit data gaps rather than inferring unseen electrical limits. The primary engineering task is to verify the manufacturer datasheet before layout signoff, especially for supply voltage, common-mode range, output sink current, offset voltage, response time, and the exact TO-5 pin map. For replacement work, engineers should require both mechanical equivalence and pin-level compatibility rather than relying only on the comparator function. A device that performs the same threshold decision but exposes different pins or output behavior is not necessarily interchangeable in production. This page distinguishes verified facts from unavailable parameters, consolidates distributor and datasheet links, and provides replacement and design guidance for engineers evaluating the LT111AH. Commercial prices are reported as of 2026-10-22 only where a source supplied a value; otherwise a quote is required.

LT1125CJ - Quad Precision Op Amp | Analog Devices | Instrumentation
LT1125CJ

LT1125CJ - Quad Precision Op Amp | Analog Devices | Instrumentation

The Analog Devices LT1125CJ is a quad low-noise, high-speed precision operational amplifier packaged in a 14-pin CERDIP. The device provides four amplifier channels in one through-hole package, making it useful when a circuit requires multiple precision signal-conditioning stages without allocating separate packages for each channel. The LT1125 family is positioned for instrumentation and other applications where low-noise, high-speed amplification and higher gain performance are important. An operational amplifier, commonly called an op amp, is an active semiconductor component that uses high gain and negative feedback to amplify small voltage differences. It belongs to the amplifier IC hierarchy, where precision operational amplifiers are selected when signal fidelity, offset behavior, bias-current characteristics, and open-loop performance matter more than the lowest possible cost or smallest footprint. The LT1125 uses a four-channel architecture, with the “quad” configuration providing four amplifier sections in one package. Its operating class is described by Analog Devices as low noise, high speed, and precision. These characteristics make it suitable for low-level sensor conditioning, instrumentation amplification stages, and analog signal chains in which multiple channels must be handled consistently. The C suffix identifies the commercial temperature-grade family, while the J suffix denotes the through-hole ceramic dual-inline package used by LT1125CJ. The manufacturer describes the LT1125 as offering higher gain, slew rate, and bandwidth than the industry-standard OP-27 and competing OP-470 families. These comparisons are relevant when upgrading an existing precision-amplifier design, but the actual signal bandwidth, noise density, input offset voltage, input bias current, input voltage range, and output swing must be checked against the system requirements before replacing another amplifier. Typical uses include four-channel instrumentation front ends, low-level transducer signal conditioning, precision measurement systems, laboratory interfaces, and factory test equipment. The LT1125CJ is particularly appropriate when a through-hole ceramic package is preferred, four amplifier channels are required, and the design benefits from the family’s stated low-noise, high-speed, and precision characteristics. It can also simplify assembly by reducing the number of amplifier packages on a board. The principal design consideration is package-level thermal management. A 14-pin CERDIP offers a larger thermal path and more forgiving assembly characteristics than a small surface-mount package, but it consumes substantially more board area. Confirm pin orientation, supply requirements, input common-mode range, output swing, stability requirements, and decoupling directly from the manufacturer datasheet before laying out the PCB. This product record combines the exact ordering information, package details, family positioning, manufacturer product information, and replacement-search results into an engineering-oriented reference. It also highlights where a genuinely pin-compatible replacement must be qualified rather than assuming that a similar amplifier has the same pinout, supply behavior, or precision performance.

LT1127CJ - Quad High-Speed Precision Op Amp | Analog Devices
LT1127CJ

LT1127CJ - Quad High-Speed Precision Op Amp | Analog Devices

Analog Devices LT1127CJ is a quad, decompensated, low-noise, high-speed precision operational amplifier packaged in a 14-pin CERDIP. The device contains four amplifiers and is stable at a closed-loop gain of 10 or higher. Its decompensated architecture provides higher slew rate and bandwidth than the LT1124 dual and LT1125 quad operational amplifiers while preserving the DC specifications of those devices. The LT1127 therefore occupies the linear-regulator-to-precision-signal-chain role where multiple channels must amplify small signals without being operated as unity-gain amplifiers. An operational amplifier is an analog integrated circuit that uses high-gain differential amplification and negative feedback to control gain, bandwidth, output impedance, and signal integrity. A precision operational amplifier adds low offset, low bias-current, and noise-related performance for instrumentation, measurement, active filtering, and signal-conditioning systems. The LT1127 is specifically a decompensated amplifier: its compensation supports stable operation at higher closed-loop gain rather than the unity-gain stability expected from conventional voltage-feedback amplifiers. The LT1127 family provides four amplifiers in one package, reducing component count and board area when several precision channels are required. Its defining performance advantage is the combination of increased AC performance with unchanged DC characteristics relative to the LT1124 and LT1125 families. The manufacturer describes the LT1126/LT1127 as high-performance, low-noise, high-speed precision op amps with stability at a gain of 10 or more. This makes the family applicable to instrumentation amplifiers, active filters, low-level sensor interfaces, and analog control loops whose architecture already provides adequate loop gain at a closed-loop gain of 10. The LT1127CJ is the 14-pin CERDIP orderable designation within the LT1127 family. A ceramic dual in-line package provides a through-hole mechanical format for industrial and legacy-style equipment, while the quad channel count supports four independent amplifier sections. Applications include four-channel sensor conditioning, multi-channel active filtering, buffered instrumentation inputs, precision signal amplification, and industrial measurement systems. The decompensated architecture makes gain planning essential: feedback networks should be designed around a minimum stable closed-loop gain of 10. Designers should account for the package's thermal environment, input and output signal limits, supply voltage, and the feedback network when using the LT1127CJ. Because the device is decompensated, using it as a unity-gain buffer is not the intended operating mode. Confirming offset, bias-current, noise, slew-rate, bandwidth, supply-current, and temperature limits in the manufacturer datasheet is necessary before fixing the production design. This product page organizes the exact LT1127CJ identity, package information, manufacturer documentation, engineering use cases, and sourcing path in one place. It also highlights the principal selection constraint—stable operation at a gain of 10 or higher—so engineers can distinguish this decompensated precision amplifier from conventional unity-gain-stable op amps before beginning PCB or schematic work.

LT1132CN - Low-Power RS-232 Transceiver | Analog Devices

The Analog Devices LT1132CN is a low-power RS-232 line transceiver with integrated drivers and receivers in a 24-pin through-hole DIP package. The verified source data identifies it as a commercial-temperature line transceiver with 24 terminals, a rectangular DIP package, and through-hole mounting. It is designed for systems that need bidirectional serial data transmission over RS-232 links, including computer serial ports, industrial control links, data-acquisition equipment, and embedded control systems. An RS-232 transceiver is an interface IC that converts between digital logic-level signals and RS-232 line-level voltages. The LT1132CN combines transmitter and receiver functions in one package, reducing the number of interface components required in a serial port. In the broader electronics hierarchy, it belongs to interface ICs, line drivers and receivers, communication transceivers, and RS-232 interface devices. Its commercial-grade classification makes it relevant to equipment operating in ordinary commercial environments, although detailed temperature limits were not present in the supplied data. The verified listing identifies the LT1132CN as a LINE TRANSCEIVER and supplies the package basics: 24 terminals, DIP package code, rectangular package shape, and through-hole terminal form. The supplied search results also associate the LT1132 family with low-power 5 V RS-232 drivers and receivers, but exact voltage, current, propagation-delay, driver-strength, receiver-threshold, and logic-level values are not provided. Those parameters should be confirmed in the manufacturer datasheet before final circuit design. The transceiver can be used to connect a host controller to an RS-232 data link, especially where a compact, multi-function interface is preferred over separate driver and receiver ICs. Because this is a through-hole DIP device, it is well suited to through-hole prototypes, legacy equipment, repair applications, and industrial controller boards where a large package and socketed assembly are acceptable. The DIP outline also simplifies inspection and replacement, but it requires more board area than a surface-mount equivalent. A key design consideration is that RS-232 uses voltage levels and signal polarity that are not directly compatible with ordinary CMOS or TTL logic. The transceiver handles that conversion, but the system still needs correct decoupling, grounding, connector protection, cable-length planning, and appropriate handling of unused enable or control pins. Because the supplied data does not specify exact pin names or all electrical limits, the LT1132CN pinout should be taken from the official datasheet rather than inferred from the package outline. This page consolidates the verified distributor and manufacturer-related links for the LT1132CN, identifies the confirmed commercial DIP package information, and separates verified facts from parameters that still require datasheet confirmation. It also records the absence of verified pricing, lifecycle, compliance, pin-level, and direct drop-in replacement data to avoid presenting unsupported engineering assumptions.

LT1167IS8 - Precision InAmp, Single-Resistor Gain, SOIC-8 | Analog Devices
LT1167IS8

LT1167IS8 - Precision InAmp, Single-Resistor Gain, SOIC-8 | Analog Devices

The Analog Devices LT1167IS8 is a low-power, precision instrumentation amplifier (InAmp) that requires only one external resistor to set any gain from 1 to 10,000, housed in an 8-pin SOIC package. Key specifications include 7.5 nV/√Hz input voltage noise density at 1 kHz, 60 µV maximum offset voltage, 1.2 V/µs slew rate, 1 MHz gain-bandwidth product, and 0.9 mA typical supply current on ±2.3V to ±18V supplies. An instrumentation amplifier is a specialized differential amplifier topology designed to extract a small differential signal riding on a large common-mode voltage. The internal three-op-amp architecture provides high common-mode rejection ratio (CMRR), high input impedance on both inputs, and a single external gain-setting resistor (RG), dramatically simplifying precision signal-chain design compared to discrete implementations. The LT1167 belongs to the analog-front-end / signal-conditioning IC category, sitting between sensors and ADCs in measurement systems where low noise and high CMRR are paramount. The single-resistor gain programmability eliminates the matched-resistor pairs required by classic InAmp topologies - any gain from G=1 (RG open) to G=10,000 (RG=60.4Ω) is set by one standard-value resistor, which simplifies calibration and reduces bill-of-material cost. The LT1167 also passes the IEC 1000-4-2 level 4 ESD specification on the inputs when used with two 5 kΩ protection resistors, making it robust for industrial sensor interfaces. Typical applications include weigh scales and load-cell bridges, ECG and biomedical front-ends, thermocouple amplifiers, industrial process-control transducer conditioning, and precision data-acquisition systems. The wide ±2.3V to ±18V supply range and 8-pin SO footprint make it a drop-in upgrade path for legacy AD620, INA128 and similar 3-op-amp InAmp sockets. When designing with the LT1167, place the gain-setting resistor close to the RG pins to minimize parasitic capacitance, and provide an output-referred filter capacitor if driving long cables to prevent capacitive loading instability. The reference pin (REF) should be driven by a low-impedance source or decoupled with 0.1 µF to ground for optimal CMRR. This page synthesizes verified distributor pricing, parametric drop-in alternatives (same-package and pin-compatible), and practical design notes that go beyond the Analog Devices datasheet table alone.

LT1179CJ - 17uA Quad Precision Op Amp | Analog Devices

Analog Devices LT1179CJ is a micropower quad precision operational amplifier supplied in a 14-pin CERDIP package. The device is optimized for single-supply operation at 5V and is also specified at ±15V supplies. Each amplifier features a maximum supply current of 17uA, maximum offset voltage of 70uV, maximum offset current of 250pA, and maximum input bias current of 5nA. A precision operational amplifier is a low-noise, high-gain analog signal-conditioning device used to amplify weak sensor, instrumentation, control, and feedback signals. The LT1179CJ belongs to the micropower operational-amplifier category, combining four amplifiers in one package with very low supply-current demand. This makes it suitable for battery-powered instrumentation and other systems where amplifier power consumption must remain small. The LT1179CJ is specified as a general-purpose, four-circuit amplifier. Its precision characteristics include low offset voltage, low offset current, and low input bias current, helping reduce signal error when the amplifier is used with sensors, transducers, or high-impedance sources. The device is intended for single-supply systems, where the output signal must be biased above ground, as well as conventional dual-supply circuits using ±15V. The LT1179CJ can be used in low-power sensor interfaces, precision signal-conditioning circuits, instrumentation amplifiers, data-acquisition front ends, battery-powered measurement systems, and low-current feedback loops. Its 17uA-per-amplifier maximum supply current is particularly useful when four active amplifiers would otherwise contribute a larger aggregate supply-current requirement. For single-supply operation, confirm the input and output common-mode range, output swing, and load requirements against the manufacturer datasheet before finalizing the biasing network. Decoupling capacitors should be placed close to the power pins, and unused amplifier channels should be configured according to the recommended stable-output method. This product page combines the manufacturer product information, distributor package identification, and application-oriented engineering guidance.

LT1206CR - 250mA, 60MHz Current Feedback Amplifier | Analog Devices
LT1206CR

LT1206CR - 250mA, 60MHz Current Feedback Amplifier | Analog Devices

Analog Devices LT1206CR is a single current-feedback operational amplifier with 250mA minimum output drive current and 60MHz bandwidth in a 7-lead DDPAK package. The device is optimized for video and other applications requiring high slew rate, wide bandwidth, and the ability to drive large capacitive loads while maintaining stable operation. Its high-impedance input is specified at 10M ohms, and its adjustable supply-current architecture provides additional control for power-sensitive designs. A current-feedback amplifier is a voltage-input, current-output feedback topology within the broader operational-amplifier and analog signal-conditioning product hierarchy. Unlike a conventional voltage-feedback amplifier, the LT1206CR controls a differential current rather than an error-voltage gain, enabling wide bandwidth and high slew-rate performance while preserving low distortion. It is positioned as an analog amplifier IC for video, communications, and signal-chain systems that need more output drive than a general-purpose op amp provides. Verified manufacturer information identifies 250mA minimum output drive, 60MHz bandwidth, a 900V/us maximum slew-rate value, 0.02% differential-gain error, and 0.17 degrees differential phase. The device operates across a wide supply range and accepts supplies up to ±15V. A shutdown function places the amplifier in a high-impedance, low-current mode, with shutdown current below 200uA, helping reduce dissipation when the circuit is inactive. The LT1206 is particularly suitable for video because it combines high bandwidth, high output current, and excellent video characteristics. It is also stable with large capacitive loads and can supply the current required by capacitive input and output networks. The adjustable supply-current feature allows engineers to balance performance and power consumption according to the source impedance, load, and operating conditions of a specific board. Typical uses include video buffering, cable-driver interfaces, active video filters, video distribution, communications equipment, and test and measurement systems. In these applications, the 60MHz bandwidth and 250mA output-current capability provide useful margin for signal transmission and load driving, while the shutdown feature supports systems that periodically disable the amplifier. When laying out the circuit, use short feedback paths, maintain the feedback network close to the amplifier, and account for the DDPAK-7 thermal-pad connection when calculating copper heat spreading. Because the exact pin names and exposed-tab assignment are not present in the supplied verified snippets, the package drawing is not populated rather than presenting an unverified pinout. Consult the official LT1206 datasheet before PCB release or substitution. This page consolidates the verified Analog Devices product information, distributor availability references, package details, and practical selection guidance for the LT1206CR. It also distinguishes device-level evidence from unresolved replacement and pricing data, helping engineers avoid treating generic op-amp alternatives as true pin-compatible drop-ins.

LT1209CS - Quad 45MHz 400V/µs Op Amp | Analog Devices
LT1209CS

LT1209CS - Quad 45MHz 400V/µs Op Amp | Analog Devices

Analog Devices LT1209CS is a quad, very-high-speed operational amplifier with 45 MHz gain-bandwidth product, 400 V/µs slew rate, and unity-gain stability in a 16-lead SOIC package. Each of its four amplifier channels uses a single-gain-stage architecture designed for accurate, fast settling. The LT1209CS operates from a wide supply range, with ±15 V operation explicitly identified as a minimum configuration, and consumes 7 mA per amplifier. An operational amplifier is a high-gain differential amplifier whose feedback network determines its behavior. The LT1209 belongs to the general-purpose operational-amplifier hierarchy, combining high speed with improved DC characteristics. It is a voltage-feedback amplifier designed to serve as a unity-gain buffer, a signal amplifier, or the active element in instrumentation and data-acquisition circuits. Compared with slower general-purpose devices, its principal advantage is rapid large-signal response rather than micropower operation. Key features include a 45 MHz gain-bandwidth product, 400 V/µs slew rate, and a 90 ns settling time to 0.1% for a 10 V step. The listed DC gain is 7 V/mV, while the maximum input offset voltage is reported as 3 mV in the LT1208/LT1209 datasheet summary. Unity-gain stability allows direct operation without compensation or added closed-loop gain, and the single-gain-stage architecture gives the device outstanding settling characteristics. The LT1209CS combines the speed of a high-speed voltage-feedback amplifier with DC performance suited to general instrumentation. Its wide supply range permits operation near ±15 V, while the minimum output swing of ±12 V into 500 ohms provides useful output range for bipolar signal chains. The 7 mA supply current per amplifier is a meaningful tradeoff: fast settling and slew performance are obtained at a higher supply current than typical low-power op amps. Typical uses include high-speed data acquisition, active filtering, sample-and-hold buffers, waveform conditioning, video or communications signal paths, and instrumentation requiring rapid settling. In a data-conversion system, the amplifier can drive or buffer an ADC input while preserving pulse amplitude and timing. In active filters, its 45 MHz bandwidth and 400 V/µs slew rate support signal paths whose operating frequency is comfortably below those limits. Designers should preserve adequate output-voltage headroom and verify capacitive-load stability with the actual output network. Input and feedback resistances also determine gain-bandwidth and noise behavior, so practical resistor values should be selected rather than relying on the nominal 7 V/mV open-loop gain. Stable reference grounding and short feedback paths are important because the device’s high speed can expose board-level parasitic capacitance. This page consolidates the available manufacturer and distributor information for the LT1209CS, distinguishes verified device characteristics from unavailable data, and provides practical selection and design guidance. It also distinguishes genuine drop-in alternatives from related package or ordering variants that should not be treated as automatic replacements.

LT1210CR

LT1210CR - 1.1A, 35MHz Current Feedback Amplifier | Analog Devices

The Analog Devices LT1210CR is a current feedback operational amplifier delivering a minimum 1.1 A of output drive current with a 35 MHz small-signal bandwidth and a 900 V/µs slew rate, housed in a 7-pin DDPAK (TO-263) surface-mount package. It operates from ±15 V supplies (single supply up to 30 V) and combines high output current with excellent large-signal characteristics, making it suitable for driving low-impedance loads such as cables, transformers, and power transistors at frequencies in the 1 MHz to 2 MHz range. A current feedback amplifier (CFA) is a class of op-amp whose inverting input impedance is intentionally low and whose small-signal bandwidth is set primarily by the feedback resistor rather than the closed-loop gain. CFAs therefore maintain near-constant bandwidth across a wide range of gains, in contrast to voltage feedback amplifiers whose gain-bandwidth product is fixed. Within the power-management and signal-chain taxonomy, the LT1210CR sits in the high-current buffer / line-driver niche: amplifier -> operational amplifier -> current feedback amplifier -> power op-amp -> analog signal chain IC. Key features of the LT1210CR include a 10 MΩ high input impedance, ±15 V supply operation, short-circuit protection, thermal shutdown, and an optional shutdown pin that pulls the quiescent current below 200 µA. The shutdown pin is internally biased to the positive rail, which allows simple open-drain (open-collector) logic control using a 5 V buffer. A wide supply range and stable operation with large capacitive loads make the device rugged in real-world cable-driving and piezo-driver circuits. Architecturally, the LT1210 uses a complementary output stage and current-mode feedback topology to achieve high slew rate independent of gain-setting resistor values. The combination of 35 MHz bandwidth and 900 V/µs slew rate allows full-power operation up to several MHz before slewing-induced distortion dominates, which is uncommon in standard op-amps of similar output current capability. Typical applications include video and RGB line drivers, twisted-pair line drivers, low-impedance cable drivers, piezo transducer drivers, headphone amplifiers, motor driver signal stages, and power-MOSFET gate drivers. The 7-pin DDPAK (TO-263) package provides a low thermal resistance (θJA ≈ 30 °C/W on a 1 in² copper pour) so that the 1.1 A output stage can be used continuously without external heatsinking at moderate ambient temperatures. When designing with the LT1210CR, pay close attention to the feedback resistor value — a 1 kΩ resistor typically yields 35 MHz bandwidth in the non-inverting configuration. Place supply bypass capacitors (≥ 0.1 µF ceramic in parallel with ≥ 4.7 µF tantalum or electrolytic) within 5 mm of the supply pins to maintain stability at high output currents. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers evaluate the LT1210CR against competing high-current op-amps.

LT1212IS - 14MHz Precision Quad Op Amp | Analog Devices

The Analog Devices LT1212IS is a four-channel precision operational amplifier with a typical gain-bandwidth product of 14 MHz, a typical slew rate of 7 V/us, and a 16-SO surface-mount package. Designed for single-supply operation, the LT1212 combines four amplifiers in one package for signal-conditioning, filtering, instrumentation, and control applications where channel count, precision, and dynamic performance are important. An operational amplifier is a voltage-feedback amplifier that uses high open-loop gain to amplify the difference between its inverting and non-inverting inputs. Within the broader semiconductor hierarchy, the LT1212 belongs to the precision operational amplifier class, a type of analog amplifier used for closed-loop signal conditioning. Its quad configuration reduces package count and provides four identical amplifier channels for systems requiring several independent analog functions. Key performance features include a 14 MHz typical gain-bandwidth product and a 7 V/us typical slew rate. According to the Analog Devices datasheet, fast settling reaches 0.01% after a 2 V step in approximately 900 ns and 1 mV after a 10 V step in approximately 2.2 us. These characteristics support accurate amplification of higher-frequency signals while preserving useful large-signal behavior in precision analog circuits. The LT1212 is the quad counterpart of the LT1211 dual amplifier. Its high-frequency performance allows a single amplifier type to cover functions that would otherwise require several separate precision op amps. The device is specified for single-supply operation, making it applicable to systems where the signal and supply rails must remain close to ground. Exact input-offset voltage, input-bias-current, common-mode range, supply range, noise, and temperature limits must be confirmed from the manufacturer datasheet before final circuit sizing. Typical uses include active low-pass filters, current-to-voltage conversion, sensor signal conditioning, sample-and-hold amplifier stages, audio preamplification, and instrumentation buffers. The LT1212IS is particularly useful when four channels can share common supply and ground connections, reducing board area compared with four individual single-amplifier packages. Designers should verify input common-mode voltage, output swing, supply voltage, stability, and load-driving limits against the operating conditions of the target circuit. Decoupling capacitors should be placed close to the power pins, and unused amplifier inputs should be configured according to the manufacturer recommendations to avoid offset errors and unnecessary output saturation. This page organizes the LT1212IS specifications, sourcing questions, application guidance, package details, and verified design considerations. It also distinguishes true pin-compatible replacements from related LT1212 family options, helping engineers identify when an alternative can preserve the existing 16-SO footprint and when a package or electrical difference requires PCB changes.

LT1214CS - 28MHz 12V/us Quad Precision Op Amp | Analog Devices
LT1214CS

LT1214CS - 28MHz 12V/us Quad Precision Op Amp | Analog Devices

Analog Devices LT1214CS is a four-amplifier precision operational-amplifier IC with a 28 MHz typical gain-bandwidth product, 12 V/us typical slew rate, and a 16-lead SOIC package. Designed for single-supply operation, the device combines four general-purpose amplifiers in one package and supports precision signal conditioning, filtering, and gain-stage applications. The verified manufacturer material identifies LT1214CS as the quad version of the LT1213/LT1214 precision amplifier family. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. The operational-amplifier category belongs to the broader analog-amplifier hierarchy and supports DC-precision signal conditioning, instrumentation, buffering, active filtering, and closed-loop control. In a feedback network, the LT1214CS can set closed-loop gain and signal polarity while using its 28 MHz bandwidth and 12 V/us slew rate to reproduce changing waveforms with relatively low delay. The verified data identifies a typical 28 MHz gain-bandwidth product and 12 V/us slew rate. It also lists fast settling to 200 uV within 500 ns after a 2 V step and to 1 mV within 1.1 us after a 10 V step. These figures make the four internal amplifiers useful when multiple channels must process comparable signals, particularly in active filters, sensor interfaces, audio paths, and control systems. The DC-precision positioning also helps reduce external trim requirements in systems where offset and drift must be controlled. Architecturally, the LT1214CS places four amplifiers in one 16-lead SOIC rather than requiring four separate packages. A typical application uses each amplifier for a distinct function, such as instrumentation amplification, active filtering, output buffering, or error amplification. The package consolidates routing over one PCB footprint while still providing independent amplifier channels. Because the verified snippets do not provide the complete electrical tables, exact input-offset voltage, input-bias current, noise density, supply-current, and common-mode-range values should be confirmed in the manufacturer datasheet before final design release. Typical uses include multichannel sensor conditioning, precision active filters, audio signal paths, instrumentation front ends, and general-purpose control loops. The quad organization is especially useful when several signals must be amplified consistently within one instrument, converter, or monitoring system. The 16-SO package allows a conventional surface-mount layout, although careful grounding and decoupling remain necessary for stable high-gain operation. The principal design consideration is to verify rail-to-rail behavior, common-mode limits, output swing, and stability requirements for the specific operating conditions. Input and output capacitors should be placed close to their associated pins, sensitive analog traces should avoid switching-current paths, and unused amplifier channels should be configured according to the manufacturer recommendations rather than left floating. This page combines verified manufacturer and distributor information with a parameter-focused application guide, sourcing guidance, and explicit data gaps. It also distinguishes the lead-free LT1214CS#PBF ordering designation from the base LT1214CS MPN instead of treating a packaging-ordering variant as a separate drop-in alternative.

LT1216CN

LT1216CN - 23MHz Quad Precision Op Amp | Analog Devices

The Analog Devices LT1216CN is a quad precision operational amplifier with 23 MHz gain-bandwidth product, 50 V/us slew rate, and single-supply operation in a 14-pin PDIP package. It is the quad version of the LT1215 family and is designed for instrumentation, signal-conditioning, filtering, and control applications that require a combination of DC precision and high-speed dynamic performance. An operational amplifier is an active analog building block that amplifies the voltage difference between its inverting and non-inverting inputs. The LT1216 belongs to the broader hierarchy of amplifier IC, instrumentation amplifier, and operational amplifier products used in precision signal chains. Its precision characteristics reduce the need for external trimming in many systems, while its high bandwidth and slew rate support accurate response to rapidly changing signals. The verified product information identifies the LT1216 as a four-circuit, bipolar, PDIP-14 precision amplifier. The family is specified at 23 MHz gain-bandwidth product and 50 V/us slew rate. The single-supply capability is useful in systems where the signal and supply rails must be referenced close to ground. The package provides four amplifier channels in one component, allowing multiple signal paths to share a common footprint and simplifying board-level layout. The LT1216 family is based on the LT1215 dual amplifier and extends the same precision amplifier architecture to four channels. The combination of high gain-bandwidth product, high slew rate, and DC precision is useful when a design must preserve small-signal accuracy while also handling waveforms with meaningful frequency content. Applications include sensor signal conditioning, active filters, low-level current-to-voltage conversion, data acquisition front ends, and general-purpose analog control. Because the LT1216CN is a monolithic four-channel device, decoupling and grounding remain important design considerations. Each supply rail should be bypassed close to the device with suitable local capacitance, and sensitive analog signals should be routed away from noisy switching nodes. The 14-pin PDIP package also requires adequate spacing and appropriate lead formation during assembly, making it more convenient for through-hole prototypes than for space-constrained surface-mount products. This product page synthesizes the verified manufacturer description, distributor identification, package information, and available comparison references for engineers evaluating the LT1216CN. Because the supplied web data does not include complete electrical tables, pricing values, or a confirmed pin-by-pin diagram, unavailable technical fields are explicitly marked rather than inferred.

LT1216CS - 23MHz Quad Precision Op Amp | Analog Devices

The Analog Devices LT1216CS is a quad precision operational amplifier with 23 MHz typical gain-bandwidth product, 50 V/µs typical slew rate, and four amplifiers in a 16-pin SOIC package. Designed by Linear Technology and offered by Analog Devices, the device combines low-noise signal-chain performance with single-supply operation. An operational amplifier is an analog building block used to amplify voltage differences, buffer signals, drive analog-to-digital converters, and implement active filters. The LT1216 belongs to the precision-op-amp hierarchy, where accurate DC behavior and fast large-signal response are useful in instrumentation, industrial measurement, communications, and test systems. It is a general-purpose precision amplifier rather than a power regulator or switching device. The verified specifications identify a 23 MHz gain-bandwidth product, 50 V/µs slew rate, and fast settling of 250 ns to 0.01% for a 2 V step. The manufacturer describes the LT1216 as a quad version of the LT1215 dual amplifier and states that the devices operate from any supply greater than 2.5 V and less than 36 V total. These figures support both precision low-frequency work and higher-bandwidth signal conditioning. The LT1216 family emphasizes DC precision and high-frequency performance. Its 23 MHz bandwidth provides useful signal amplification bandwidth, while the 50 V/µs slew rate improves response to step-like signals. The manufacturer’s published settling data gives 250 ns typical settling to 0.01% after a 2 V step and 480 ns after a 10 V step to 1 mV, making circuit simulation and feedback-loop design important. Typical uses include instrumentation amplifiers, active filters, buffer stages, communication interface circuits, data-converter front ends, and precision control systems. The quad format can reduce the number of external amplifier packages when four independent channels are required, although input, output, supply, and common-mode limits must still be checked independently. For PCB design, keep input and feedback traces short, use a solid ground reference, place compensation or decoupling components according to the manufacturer’s application guidance, and verify stability with the selected gain and load. For replacements, the LT1215 is a dual-package family member but is not a pin-compatible substitute for this 16-pin quad device; package and pin count must be checked before any redesign.

LT1230CS - Quad 100MHz Current Feedback Amplifier | ADI

The Analog Devices LT1230CS is a quad 100 MHz current-feedback amplifier with four amplifiers in a 14-pin SOIC package, a 4 V to 30 V supply range, and operation from single or dual supplies. Its 100 MHz bandwidth supports high-speed signal conditioning, while the current-feedback architecture is suited to low-gain stages with high slew rate. The device is identified by the CS commercial-temperature ordering code. A current-feedback amplifier is a voltage-feedback amplifier variation that controls bandwidth and stability through feedback impedance. Current-feedback amplifiers belong to the broader operational-amplifier, analog-amplifier, and semiconductor hierarchies. They are frequently selected where conventional voltage-feedback amplifiers require gain compensation across multiple closed-loop gains or where rapid large-signal response is more important than rail-to-rail input or output operation. The verified source data identifies 100 MHz bandwidth, a 2500 V/µs slew-rate figure for the CS#TR variant, 30 mA output-drive capability, 0.04% differential gain, and 0.1° differential phase. It also reports 25 MΩ input impedance with 3 pF input capacitance. These figures make the LT1230CS appropriate for video, communications, instrumentation, and general high-speed analog interfaces when the circuit operates within the verified supply and package limits. The CS package is a 14-pin SOIC measuring 0.154 inch, or 3.90 mm, in body width. The quad topology lets one device provide four high-speed amplifier sections while reducing package count, although common power, ground, bypass, and thermal-management requirements still apply. Supply decoupling should be placed close to the device, and unused amplifier sections should be configured according to the manufacturer guidance rather than left floating. Typical applications include video buffering, high-speed data acquisition, communications-interface signal conditioning, active filtering, and instrumentation. The LT1230CS is particularly relevant where the required bandwidth and slew behavior outweigh the need for rail-to-rail operation. Designers should verify package pin assignments, recommended feedback networks, output loading, and supply sequencing against the official manufacturer datasheet before layout release. This page combines verified manufacturer and distributor information with package, application, and design guidance. Because no verified internal pricing or complete pin-level datasheet extract was supplied, missing engineering values are marked rather than inferred. The result is intended to help engineers identify whether the LT1230CS fits a design before obtaining the complete official datasheet and validating the application circuit.

LT1256CN - 40MHz Video Fader Amplifier | Analog Devices
LT1256CN

LT1256CN - 40MHz Video Fader Amplifier | Analog Devices

The Analog Devices LT1256CN is a 40 MHz video fader and DC gain controlled amplifier: a two-input, one-output current-feedback amplifier whose linear control circuit sets how much each input contributes to the output, offered in a 14-pin PDIP (N-14) through-hole package. Its headline specifications are 40 MHz small-signal bandwidth, 300 V/us slew rate, and single-supply operation from 5 V to 30 V. The manufacturer lists the LT1256 as PRODUCTION, with a lead-free ordering code (LT1256CN#PBF) also offered. A video fader is a controlled-gain summing amplifier used to blend two signal sources smoothly and repeatably, typically in broadcast video equipment, audio consoles, keyers, and AGC loops. The LT1256 belongs to the current-feedback amplifier family, itself a subset of operational amplifiers, inside the broader category of analog signal-conditioning integrated circuits. Its linear control characteristic means a control voltage produces a proportional change in signal contribution, which makes the part well suited to automated mix and fade systems rather than purely manual potentiometer fading. Key features include two independently weighted inputs, DC gain control in addition to the fading function, 40 MHz bandwidth with 300 V/us slew rate for full-amplitude video signals, and a wide 5 V to 30 V supply range that allows the part to run from legacy analog rails or modern low-voltage systems. Because the control loop is linear rather than logarithmic, the part can also be used as a programmable attenuator, an analog multiplier element in filter and modulation blocks, and as the forward path of a closed-loop gain-control system. The current-feedback topology is the key architectural point: in a current-feedback amplifier the closed-loop bandwidth is largely set by the external feedback resistor rather than by the closed-loop gain, so large-signal performance stays consistent as the control voltage changes gain. The result is that signal amplitude does not visibly change color or slew rate while fading, and distortion stays low at large video amplitudes. Typical applications include broadcast video switchers and mixers, video keyers and titlers, audio mixing consoles, automatic gain control front ends for cameras and RF receivers, lab-grade attenuator and filter test setups, and general instrumentation where a variable, precisely weighted gain element is needed. When laying out an LT1256 design, treat the feedback resistor and the compensation capacitor as part of the gain-setting network: keep them close to the device, use a 0.1 uF ceramic bypass on each supply rail, and verify output swing headroom at the highest control voltage, because the output typically approaches the supply rails on a single-supply configuration. This page consolidates manufacturer specifications, package and lifecycle detail, verified drop-in alternatives, comparison parameters, and practical layout guidance in one place, so engineers can qualify the LT1256CN for a new mixer or fade block without cross-checking several documents.

LT1260IS - Triple 130MHz Current Feedback Amp | Analog Devices

LT1260IS - Triple 130MHz Current Feedback Amp | Analog Devices

Analog Devices LT1260IS is a triple current-feedback operational amplifier rated for 130 MHz operation, supplied in a 16-lead SOIC package. Each of its three independent amplifiers supports a wide supply range from a single 5 V rail through ±15 V, while active supply current is 5 mA per amplifier. The LT1260IS also provides shutdown control, allowing unused amplifiers to be placed into a zero-supply-current state for power conservation. A current-feedback operational amplifier is a high-speed voltage-amplifier topology whose closed-loop bandwidth depends primarily on the feedback resistor rather than the closed-loop gain. Current-feedback amplifiers are commonly used for video, communications, instrumentation, and other signal chains requiring large slew rate, low distortion, and reliable drive into low-impedance loads. The LT1260 family combines these characteristics with a triple amplifier configuration, allowing one device to support several independent channels. The LT1260IS provides 90 MHz small-signal bandwidth, more than 30 MHz of 0.1 dB gain-flatness bandwidth, and a 1600 V/µs high slew rate. These figures distinguish it from general-purpose operational amplifiers whose bandwidth and transition performance are usually much lower. The combination is particularly useful when processing composite video, driving short cable runs, amplifying high-speed control signals, or operating several phase-related channels in compact equipment. Each amplifier combines a current-feedback core with shutdown capability. When shutdown is asserted, the corresponding amplifier draws approximately 0 µA from the supply, reducing the overall power requirement of systems that do not need all three channels active. The architecture is intended to maintain linearity while driving cables and other low-impedance loads, making channel-to-channel implementation straightforward when identical gain-setting networks and routing practices are used. Typical uses include RGB video amplification, low-impedance cable drivers, communications-interface signal conditioning, industrial control interfaces, and instrumentation. In a three-channel RGB application, the three amplifiers can process red, green, and blue signals in parallel while preserving consistent bandwidth and slew capability across the channels. The same arrangement can support three-coordinate control, test, or monitoring channels where independent outputs are required. PCB implementation should prioritize short feedback loops, symmetrical routing, solid ground-plane continuity, and careful decoupling. Place the amplifier supply bypass capacitors close to the supply pins and keep feedback resistors close to the relevant output and inverting-input pins. Because a current-feedback amplifier relies on a low-impedance feedback network, route both sides of each feedback connection over continuous ground and avoid shared narrow copper paths between channels. This page organizes the LT1260IS specifications, package information, practical application guidance, and verified same-footprint alternatives for faster engineering selection. It also highlights shutdown, bandwidth, gain-flatness, slew-rate, and power-consumption considerations that help engineers distinguish this triple current-feedback amplifier from lower-speed general-purpose devices.

LT1281IJ

LT1281IJ - 5V Dual RS-232 Transceiver, 16-DIP | ADI

The Analog Devices LT1281IJ is a low-power 5 V RS-232 dual driver and dual receiver interface IC packaged in a 16-pin DIP. The verified product data identifies a 2/2 transceiver configuration, bipolar RS-232 technology, a 5 V supply, and an industrial operating-temperature grade. Its through-hole rectangular package supports conventional PCB insertion and industrial equipment designs where a surface-mount alternative is unnecessary. A transceiver combines a line driver and line receiver into one interface component. RS-232 is a differential-enough, single-ended serial interface defined by voltage levels and circuit behavior rather than a balanced differential physical signal. In the signal chain, the driver translates digital logic levels to RS-232-level voltages, while the receiver converts incoming RS-232 signals back to logic levels. The dual arrangement provides two channels in one IC and can reduce board area relative to separate single-channel devices. The LT1281 family is associated with low-power operation and 0.1 uF external-capacitor support according to the Analog Devices product page. The verified material specifically names the LT1281IJ as an industrial-temperature, 16-terminal DIP variant. Operating temperature is listed as -40 C to +85 C. Other electrical details such as driver output levels, receiver thresholds, data rate, quiescent current, and propagation delay were not included in the supplied verified text and therefore require confirmation from the manufacturer datasheet before release. Typical uses include RS-232 ports in industrial control equipment, data acquisition systems, test instruments, barcode readers, legacy computers, and embedded serial-console links. The receiver may also be useful where a system needs RS-232 receive conversion independently of the driver. Designers should validate signal amplitude, capacitance, cable length, grounding, and compatibility with the connected equipment. Do not substitute a TTL-only transceiver because logic-level compatibility does not establish RS-232 compliance. This 16-DIP device is most appropriate when through-hole assembly, industrial-temperature operation, and a dual RS-232 channel are priorities. Surface-mount systems should use a verified pin-compatible DIP alternative if one exists, whereas different package families require layout changes. This page separates supplied facts from unverified parameters and avoids inferring electrical values that were not present in the retrieved source material.

It supports operation above 120 kbaud and is designed for notebook and palmtop computer interfaces. An RS-232 transceiver is an interface IC that combines line drivers and receivers for serial data transmission over the RS-232 standard. The LT1342 belongs to the broader line-driver/receiver and interface-IC hierarchy, converting between digital logic levels and RS-232 signal levels. Its 3 V logic interface allows connection to modern low-voltage digital systems while the RS-232 side operates from a 5 V supply. The verified product information identifies three drivers, five receivers, 0.2 µF charge-pump capacitors, 1 µA shutdown supply current, low-power driver disable, and ESD protection exceeding ±10 kV. The device also operates above 120 kbaud with heavy capacitive loads, supports 250 kBaud operation for 1000 pF, and is pin compatible with the LT1137A. These features make it suitable for compact serial links where low supply current and direct 3 V logic interfacing are important. The LT1342CG is packaged as a 28-pin SSOP from Linear Technology, now part of Analog Devices. The “G” package code and SSOP form factor are identified in distributor and cross-reference results. The device also supports shutdown, allowing drivers and receivers to assume high-impedance states and reducing supply current to near zero. This is useful for portable equipment where system power conservation and bus isolation affect battery life. Typical applications include notebook computers, palmtop computers, and other equipment requiring an RS-232 port with a 3 V host logic connection. The 0.2 µF charge-pump capacitors help reduce external capacitor size, while the driver-disable function allows individual transmitters to be placed into a low-power state. The device is intended for systems where EIA RS-232 compliance, low supply current, and compact packaging are priorities. When laying out a board, place the charge-pump capacitors close to their associated pins and preserve the verified package pin assignments. Confirm the interface voltage levels, baud rate, capacitive loading, and shutdown-control polarity in the system specification. The LT1342CG is an interface IC rather than a power semiconductor, so a safe-operating-area specification does not apply.

It is supplied in a 14-pin SOIC package for surface-mount industrial, instrumentation, communications, and signal-conditioning designs. The LT1353 family combines the slewing behavior associated with current-feedback amplifiers with matched high-impedance inputs, while retaining conventional operational-amplifier signal handling. An operational amplifier is an analog integrated circuit that amplifies the difference between two input voltages. In the broader signal-chain hierarchy, the LT1353CS belongs to the operational amplifier, analog amplifier, and signal-conditioning IC categories. Its combination of low power consumption and high bandwidth is useful when a circuit must preserve small, rapidly changing signals without consuming a large supply current. The LT1353 provides four amplifiers in one package, making it suitable for multichannel filters, sensor interfaces, buffer stages, and control loops. The 3 MHz gain-bandwidth product supports higher closed-loop bandwidth than a general-purpose low-power amplifier, while the 200 V/us slew rate improves response to fast voltage transitions. The 250 uA supply-current specification is particularly important in portable instrumentation and battery-powered systems where each amplifier contributes to the overall power budget. The device is based on a high-speed, low-power architecture with high-impedance matched inputs. These characteristics make the LT1353CS useful in applications requiring more bandwidth than conventional micropower amplifiers while retaining a low quiescent-power footprint. Users should account for the amplifier’s input-noise performance, output-drive capability, stability requirements, and supply-voltage limits when designing precise analog front ends. Typical uses include low-frequency instrumentation, active filters, current-to-voltage conversion, sensor signal conditioning, and general-purpose analog amplification. In portable measurement systems, the quad organization can reduce board area by consolidating four gain stages into one package. The device is also suitable for industrial control modules where low supply current helps limit heat generation and supports longer operating intervals in field equipment. For layout, place the bypass capacitor close to the supply pins and route sensitive input signals away from power and output paths. Check the manufacturer datasheet pinout and recommended application circuit before assigning PCB nets. If the output must drive a long cable, capacitive load, or ADC input, verify the resulting stability and settling behavior rather than relying only on slew-rate and bandwidth figures. This product summary combines the manufacturer device description, package information, and cross-reference results to support engineering selection. It highlights the LT1353CS balance of low supply current, 3 MHz bandwidth, and 200 V/us slew rate while identifying the verification points that matter when replacing or integrating a quad precision analog amplifier.

The principal features include 12 MHz gain-bandwidth product, 400 V/µs slew rate, 1.25 mA maximum supply current per amplifier, and operation from ±18 V according to the Arrow listing. The amplifier is unity-gain stable and supports capacitive loading through the C-Load operating approach. Input voltage noise is specified at 10 nV/√Hz, while maximum input offset voltage is 800 µV and maximum input bias current is 300 nA. The LT1355/LT1356 family uses a voltage-feedback topology with matched high-impedance inputs and advanced bipolar complementary processing. Because the devices are unity-gain stable, they can be used directly as conventional voltage amplifiers without external compensation. Their combination of bandwidth, slew rate, and supply current is intended to provide a better performance balance than older devices with comparable bandwidth, although exact noise, offset, and bias-current values vary with the selected operating conditions. Typical uses include low-power voltage-feedback stages, video and instrumentation signal chains, analog control loops, active filters, and general high-speed buffering. In instrumentation systems, the four amplifiers can implement multiple gain or filtering channels in one package. The 400 V/µs slew rate supports rapidly changing large-signal waveforms, while the 12 MHz bandwidth allows operation at substantially higher frequencies than low-bandwidth precision amplifiers. When designing around the LT1356CN, verify the external circuit against the actual signal amplitude and frequency. Large outputs at high frequency can require more output-current capability than the small-signal parameters suggest, while capacitive loading can affect stability. The 14-pin PDIP package is not lead-free; compare this ordering option with the documented LT1356CN#PBF lead-free-finish variant when procurement rules require lead-free termination. This page consolidates the verified manufacturer and distributor details, separates known LT1356CN data from missing parameters, and identifies a same-package ordering alternative. It also provides application guidance and design cautions that help engineers evaluate the amplifier without treating incomplete distributor metadata as an exact bill of materials.
