LM258AD - Dual 30V 700kHz Op Amp | Texas Instruments
The Texas Instruments LM258AD is a dual, internally frequency-compensated operational amplifier designed for low-power operation from a single supply. It combines a 30 V maximum supply rating, 700 kHz gain-bandwidth product, 1.1 MHz unity-gain bandwidth, and approximately 500 uA supply current per amplifier in an 8-pin SOIC package. The device provides two independent amplifiers in one package and operates over the -25°C to 85°C temperature range. An operational amplifier is an analog signal-conditioning IC that uses high open-loop gain to amplify the difference between voltages applied to its inverting and non-inverting inputs. The LM258AD belongs to the operational-amplifier family within the broader linear-amplifier and analog-signal-processing hierarchy. Its internally frequency-compensated architecture eliminates the need for an external compensation capacitor in typical closed-loop configurations. Key features include a large DC voltage gain of 100 dB, a 1.1 MHz unity-gain bandwidth, low input bias current of 20 nA, and supply current that remains essentially independent of supply-voltage magnitude. The two amplifiers can be used in non-inverting, inverting, comparator, summing, difference, and general feedback configurations. The single-supply capability also supports battery-powered and industrial signal-conditioning equipment. Each amplifier is intended for operation over a wide supply range, with the verified manufacturer description identifying a 30 V maximum supply voltage and a -25°C to 85°C operating-temperature range. Internal frequency compensation makes the device suitable for straightforward fixed-gain implementations without an additional compensation network. Engineers should still account for input common-mode limits, output swing, stability, input offset, and output-current limitations according to the manufacturer datasheet. Typical applications include transducer and sensor-signal conditioning, low-current industrial control, audio preamplification, bridge-amplifier interfaces, and power-supply feedback networks. The dual configuration saves board area when two low-frequency analog channels are required. Compared with a switching regulator or a modern rail-to-rail amplifier, the LM258AD prioritizes low quiescent current, wide supply-voltage headroom, and straightforward single-supply operation. When laying out the circuit, keep input and feedback paths short and place compensation or filtering capacitors close to their associated pins when required by the selected topology. Check output-current demand and input common-mode range against the actual supply voltage. Do not assume rail-to-rail input or output behavior; the available headroom and output swing are important constraints in low-voltage designs. This page consolidates the verified manufacturer specifications, distributor availability information, package details, and practical selection guidance. It also distinguishes pin-compatible alternatives from merely similar amplifiers and highlights missing electrical data explicitly rather than estimating values that are not established by the supplied sources.
LM258AH - Dual 30V Low-Power Op Amp | STMicroelectronics
STMicroelectronics LM258AH is a dual, low-power operational amplifier designed for single-supply operation over a wide voltage range, with two independent, internally frequency-compensated amplifiers in an 8-lead TO-99-8 metal package. The LM258 family supports input voltages up to 30 V, operating frequency up to 700 kHz, and an industrial ambient-temperature range of -25 °C to +85 °C. The LM258AH ordering suffix identifies the wire-lead TO-99-8 industrial-temperature configuration. An operational amplifier, or op amp, is a high-gain analog building block used to amplify small voltage signals. Within the wider semiconductor hierarchy, the LM258AH is an analog integrated circuit and a dual operational amplifier. Its two independent channels can support signal conditioning, feedback control, voltage comparison, and general-purpose analog amplification without requiring a split-supply arrangement. The key features of the LM258AH include two amplifiers in one package, internal frequency compensation, and a maximum input voltage of 30 V. The LM258 family is designed around a 700 kHz gain-bandwidth characteristic, while the LM258A version has an input offset voltage specified as 3 mV by the cited manufacturer information. The low-power architecture is intended for applications that require wider supply-voltage tolerance than conventional low-voltage single-supply op amps. The internally compensated architecture simplifies closed-loop amplifier design because it avoids the external compensation components normally required by higher-gain parts. Independent channels may also be used for unrelated signal paths, although common supply pins mean both channels share the same operating rail and thermal environment. Designers should still verify output swing, input common-mode range, output-current capability, and stability against their actual source and load impedances. Typical uses include industrial process-control loops, sensor-signal conditioning, low-frequency filter stages, comparators, and general analog signal chains. The wide operating-voltage capability can simplify legacy and industrial designs that operate from higher single rails. The 700 kHz bandwidth is appropriate for low-frequency precision and control tasks, but it is generally not the preferred choice for high-speed video, RF, or wideband data-acquisition requirements. The principal design considerations are supply decoupling, input common-mode limits, output swing, and thermal behavior. Place the supply bypass capacitor close to the device and avoid driving outputs into hard clamps except where the application intentionally requires saturation. Verify the complete circuit against the STMicroelectronics LM258 datasheet, particularly for AC output current, noise, offset voltage, and load-capacitance stability. This product page consolidates the verified manufacturer and distributor information for the LM258AH and distinguishes the TO-99-8 metal-package option from surface-mount and other package variants. It also provides compatibility-focused replacement guidance, practical circuit considerations, and a specification comparison structured around engineers evaluating an existing TO-99-8 dual-op-amp design.
LM258D - Dual 30V Operational Amplifier | STMicroelectronics
The STMicroelectronics LM258D is a dual, internally frequency-compensated operational-amplifier IC with two independent amplifiers, a 30 V maximum supply rating and a 700 kHz gain-bandwidth product. Each amplifier is designed for general-purpose signal conditioning from single or split supplies. The device is packaged for surface mounting in an 8-pin SOIC and is identified by the DigiKey listing as a standard, general-purpose, two-circuit amplifier. The supplied source data confirms the 30 V and 700 kHz headline ratings through Texas Instruments’ LM258 family page, but it does not provide a complete STMicroelectronics parameter table. An operational amplifier is a voltage-gain element that uses external feedback to control closed-loop behavior. The LM258D belongs to the dual operational-amplifier hierarchy and contains two independent amplifiers in one package. Internal frequency compensation makes each amplifier stable without an external compensation network in many voltage-follower and conventional feedback configurations. Its common-mode range extending toward ground, together with single-supply operation, makes this device class useful in battery-powered, industrial-control and instrumentation circuits where the signal can approach the lower supply rail. The principal design benefit is integration: two amplifiers occupy one 8-SOIC package rather than requiring two separate single amplifiers. Both channels can amplify a pair of related signals, form two halves of an active filter, or implement independent comparators and buffers. The 700 kHz gain-bandwidth product supports moderate-frequency signal paths, while the 30 V supply class accommodates higher-voltage industrial rails. Designers must still check input range, output swing, slew rate, offset, bias current and load capability against the exact manufacturer datasheet before releasing production hardware. Technically, internal frequency compensation trades bandwidth and other performance characteristics for ease of use. Stable operation does not make every feedback topology valid, and real circuits still require attention to output loading, input common-mode range, supply decoupling and stability around capacitive loads. Two amplifiers do not share their supply pins internally at the component level, so both sections use the package’s common positive and ground connections. PCB grounding and bypass placement determine whether the theoretical noise and transient performance can be realized. Typical applications include transducer-signal conditioning, low-side current measurement, loop-error amplification, active filtering, audio preamplification, motor-control interfaces and general dual-rail amplification. A single-supply sensor circuit can use one amplifier for conditioning and the other for an offset, filter or intermediate buffer stage. Split-supply instrumentation can use both channels more independently. Compared with modern low-voltage rail-to-rail amplifiers, the LM258D trades compactness and precision for its wide-supply capability and straightforward general-purpose use. When designing around the LM258D, place the supply bypass capacitor close to the IC and route each amplifier’s inputs and outputs to minimize leakage and feedback-loop pickup. Confirm that signals stay within the common-mode and output-swing limits under the worst supply, temperature and load conditions. Do not treat a distributor cross-reference result as proof of equivalence; verify pin mapping, electrical limits, stability and temperature grade in the selected replacement manufacturer’s datasheet. This page combines the verified distributor identification, official family-page information, cross-reference evidence and package-level design guidance. It distinguishes confirmed facts from parameters that were not supplied, avoiding invented precision while helping engineers evaluate LM258D procurement, replacement and circuit-integration decisions.
LM258DG - Dual 1 MHz Op Amp, 3-32 V | onsemi Industrial
The onsemi LM258DG is a dual general-purpose operational amplifier with two amplifier circuits, a 1 MHz gain-bandwidth product, a 0.6 V/µs slew rate, and an operating supply range of 3 V to 32 V. The device is supplied in an 8-pin SOIC package. Its low-power design, common-mode input range extending toward ground or VEE, and support for single-supply or split-supply operation make it suitable for industrial control, instrumentation, sensor conditioning, and low-frequency signal-processing systems. An operational amplifier, or op amp, is a voltage-gain building block within analog and mixed-signal electronics. A dual op amp contains two amplifiers in one package, allowing one device to implement two independent signal paths or a differential stage. The LM258DG belongs to the operational-amplifier hierarchy: dual operational amplifier, general-purpose amplifier, analog IC, and ultimately semiconductor. Its broad supply range accommodates conventional industrial rails, while its ground-referenced input capability simplifies designs powered from a single supply. Key verified characteristics include two amplifier circuits, 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, and operation from 3 V to 32 V. The listed operating temperature range is -25 °C to 85 °C. Because the gain-bandwidth product is 1 MHz, the device is best suited to low-frequency amplification, buffering, comparators, and general feedback-control loops rather than high-speed signal processing. The LM258 architecture derives from the circuit designs used in quad operational amplifiers. This dual configuration provides functional flexibility while limiting package count and board area. Single-supply operation allows the input and output signals to remain near the lower supply rail, and split-supply operation permits bipolar-style signal paths. The verified operating range supports both 3 V minimum-supply designs and higher-voltage industrial systems. Typical applications include sensor signal conditioning, transducer amplification, current-loop interfaces, low-frequency active filters, and general-purpose analog buffers. Its two channels can also be used together as a differential amplifier when the circuit requires matched amplifier functions in one package. Applications should account for the 1 MHz bandwidth and 0.6 V/µs slew rate when setting gain, bandwidth, and expected output slew behavior. A key design consideration is verifying input and output voltage excursions for the selected single- or split-supply configuration. Decoupling and stability should be implemented around the circuit required by the ON Semiconductor LM258 datasheet and the particular feedback network. Because detailed pin names, offset voltage, input bias current, and noise figures were not supplied in the verified data, those values must be confirmed before production release. This page consolidates verified distributor specifications, sourcing information, same-package replacement candidates, and practical selection guidance. It adds engineering context for supply-range, bandwidth, packaging, and replacement decisions while clearly separating verified facts from unavailable parameters.
LM258DR - Dual 30V Operational Amplifier | STMicroelectronics (Tape & Reel)

LM258H - Dual 30V 700kHz Op Amp | Texas Instruments
The Texas Instruments LM258H is a dual general-purpose operational amplifier with a 30 V supply rating, 700 kHz gain-bandwidth product, and operation from -25°C to 85°C. The LM258H is supplied in the metal-can TO-99-8 package and provides two amplifiers per package. Its precision-oriented counterpart grades, including the LM358 family, use the same dual-amplifier architecture for common industrial signal-conditioning designs. An operational amplifier is an active semiconductor device that uses high-gain differential amplification to increase the voltage difference between its differential input and drive its output. Operational amplifiers belong to the amplifier IC hierarchy and are commonly used in sensor interfaces, buffer stages, integrators, comparators, and control loops. The LM258 family is positioned as a general-purpose bipolar amplifier rather than a high-speed, low-noise, or precision-specific device. The manufacturer identifies the LM258 family as dual, 30 V, 700 kHz operational amplifiers. The LM258H ordering variant is associated with the TO-99-8 metal-can package, while the broader LM258 family also includes other package and temperature options. The verified distributor listing describes LM258H as a two-circuit amplifier in a TO-99-8 package. The H suffix is used in the manufacturer ordering information, but individual suffix-specific electrical values must be confirmed against the ordering table in the manufacturer datasheet. The 700 kHz gain-bandwidth product is the principal verified speed parameter. It describes the approximate closed-loop bandwidth available for unity-gain operation under the stated test conditions, subject to the manufacturer datasheet's load and test assumptions. The 30 V rating identifies the device as suitable for higher-voltage analog signal chains than basic low-voltage single-supply amplifiers, provided the selected grade and supply arrangement meet the complete datasheet limits. Operating temperature is specified from -25°C to 85°C for the LM258 family. Typical uses include buffered sensor signals, low-frequency active filters, analog summing and difference amplifiers, current-loop buffering, audio and communications signal conditioning, and general industrial control interfaces. Because the verified data does not provide output-current, input-offset, noise, slew-rate, load-current, common-mode, or package-dimension values, those parameters should not be inferred for design calculations. Engineers should use the manufacturer datasheet for the exact LM258H grade limits and test conditions. The main design consideration is ensuring that the selected dual amplifier's pinout, supply voltages, input common-mode range, output swing, and load conditions match the completed analog design. TO-99-8 is a through-hole metal-can package, so PCB footprint selection and mechanical clearance require the package drawing rather than a modern SMD assumption. Decoupling, grounding, and stable feedback compensation remain necessary even when using a general-purpose amplifier. This page combines the verified manufacturer product identity, distributor package information, ordering context, and design-oriented interpretation. It also distinguishes verified LM258 family facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers move from part selection to a qualified schematic without inserting unsupported assumptions.
LM258N - Dual 32 V 700 kHz Op Amp | Amplifier IC
The LM258N is a dual, general-purpose operational amplifier designed for single-supply operation over a 3 V to 30 V range, with a stated 32 V maximum supply rating in the verified product data. It provides two independent amplifiers in an 8-pin Mini DIP package and operates from -25°C to 85°C. Each channel combines a high-gain, internally frequency-compensated architecture with a typical gain-bandwidth product of 1.1 MHz and a typical slew rate of 0.6 V/µs. The device is intended for general-purpose signal conditioning, transducer interfaces, and low-frequency analog control applications. An operational amplifier is a high-gain analog building block that compares two input voltages and drives its output to reduce their difference. A differential input amplifier, voltage follower, comparator-style interface, or control loop can be built around the LM258N when the required bandwidth, slew rate, supply voltage, and input/output range fit the device. The LM358-family architecture also allows operation from a single supply or split supply, making it useful in systems whose signal is referenced near ground. Verified product information identifies the LM258-N as a dual 32 V, 700 kHz operational amplifier with -25°C to 85°C operation. The related LM258N distributor listings identify an 8-pin Mini DIP package and a general-purpose dual amplifier configuration. The device is therefore suited to industrial and instrumentation circuits where a through-hole package and wide supply range are useful, provided the circuit designer checks the exact manufacturer datasheet for input common-mode limits, output swing, supply current, offset voltage, and thermal limits. The internally compensated amplifiers simplify implementation of unity-gain and conventional inverting or non-inverting stages because no external compensation network is required for ordinary closed-loop use. The 1.1 MHz gain-bandwidth product supports many low-frequency signal paths, while the 0.6 V/µs slew rate limits large-signal response. These characteristics make the LM258N more appropriate for instrumentation, buffering, and control than for high-speed signal chains. Typical uses include sensor signal conditioning, low-frequency active filters, audio and communications interface stages, analog control loops, and general dual-amplifier boards. In a single-supply circuit, the input and output signal ranges must remain inside the device's allowable common-mode and output-swing limits. The 8-pin DIP package also favors through-hole prototyping and repairable industrial assemblies. For PCB layout, keep input and feedback paths short, provide a solid ground reference, and place decoupling capacitors close to the supply pins. Avoid placing noisy switching nodes beside high-impedance input traces. Because the verified data does not provide every electrical limit, exact compliance status, pricing, or an official pin mapping for the generic LM258N ordering code, those details remain marked as data needed rather than inferred.
LM258NG - Dual 1MHz Operational Amplifier | onsemi
onsemi LM258NG is a dual, general-purpose operational amplifier with a 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, and operation from 3 V to 32 V in an 8-pin PDIP package. The device provides two amplifier circuits in one through-hole package and supports single-supply or split-supply operation. Its common-mode input voltage range extends toward ground or VEE, making it suitable for industrial, instrumentation, control, and signal-conditioning systems where single-rail operation is advantageous. An operational amplifier is a high-gain differential amplifier used to amplify, buffer, compare, or integrate signals. The LM258NG belongs to the dual general-purpose operational-amplifier class and within the broader hierarchy of analog ICs, analog signal-chain components, and semiconductor devices. Unlike rail-to-rail precision amplifiers, its practical input and output ranges depend on its supply voltage and circuit configuration. Designers should therefore evaluate common-mode range, output swing, input bias current, and load capability against their signal levels. The principal verified characteristics are a 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, dual-circuit construction, and a 3 V to 32 V operating supply range. The low-power-drain architecture is useful in battery-powered or space-constrained equipment, while the common-mode range extending to ground or VEE improves usefulness in systems powered from one positive rail. The 8-pin PDIP package also supports conventional through-hole assembly and socket-level serviceability. The LM258NG architecture is suited to general-purpose feedback stages rather than high-speed signal chains. A 1 MHz gain-bandwidth product provides usable bandwidth at modest closed-loop gains, while the 0.6 V/µs slew rate limits how quickly output voltage can follow a changing input. In gain configurations with substantial noise gain, the available closed-loop bandwidth is lower. Stable feedback-network design and appropriate output loading are therefore necessary to avoid oscillation or slew-limited operation. Typical uses include low-frequency sensor signal conditioning, industrial control-loop amplifiers, audio preamplification, comparators with external hysteresis, and buffered instrumentation inputs. The dual configuration can implement two independent amplifier sections on one PCB. In a single-supply circuit, input and output grounding must be referenced carefully because the common-mode range reaches ground or VEE but is not necessarily a rail-to-rail input specification. A key design consideration is power-supply decoupling: place a suitable bypass capacitor close to each supply pin and route return currents without splitting analog ground paths. Check output swing and load current at the lowest supply voltage, and use output isolation when driving capacitive loads. These checks are especially important because the available verified data does not specify detailed offset, bias-current, thermal, or output-drive limits. This page consolidates verified distributor specifications, package information, practical application guidance, and verified web-data drop-in candidates. It also distinguishes confirmed facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers identify the LM258NG quickly while avoiding unsupported assumptions.
LM258P - Dual 30 V 700 kHz Op Amp | Texas Instruments
The Texas Instruments LM258P is a dual, internally frequency-compensated operational amplifier with a 30 V supply rating, 700 kHz gain-bandwidth product, and operation from -25°C to 85°C, housed in an 8-pin PDIP package. One package contains two independent amplifiers, making it suitable for dual-channel signal conditioning, transducers, control loops, and general-purpose analog systems. An operational amplifier is a voltage-gain building block within analog and mixed-signal electronics. The LM258P belongs to the bipolar operational-amplifier family, combining differential inputs, high voltage gain, internal frequency compensation, and common operation from a single or split supply. Its two independent channels allow simultaneous amplification, filtering, buffering, or feedback control without requiring two separate amplifier packages. The verified source data identifies a wide supply-voltage operating range, high DC voltage gain, unity-gain bandwidth, low supply current, and low input-bias current. The search results specifically identify 100 dB large DC voltage gain, 1.1 MHz unity-gain bandwidth, approximately 500 µA supply current per amplifier, and approximately 20 nA input-bias current. These characteristics make the device relevant to instrumentation where useful closed-loop accuracy is more important than very high speed. Each amplifier is independently compensated, allowing normal operation without external frequency-compensation components. Input and output-device choices support practical single-supply and split-supply arrangements, while the dual configuration can reduce board area in paired channels. Nevertheless, output-current capability, common-mode limits, input-offset behavior, noise, and stability should be checked against the complete manufacturer datasheet before precision or load-heavy use. Typical uses include transducer signal conditioning, low-frequency active filters, sensor amplification, instrumentation amplifiers, sample-and-hold interfaces, and industrial control loops. The 8-pin PDIP package is appropriate for through-hole assembly and prototypes, and its wide temperature coverage supports equipment operating across industrial temperature ranges. PCB design should keep input and feedback paths short, provide adequate supply bypassing, and maintain a stable reference or mid-supply point when the output must remain biased above ground in single-supply operation. Avoid relying on the verified snippets for load-current or saturation limits; those values require the complete LM258 manufacturer datasheet. This page consolidates the verified LM258P identity, package, temperature, supply, bandwidth, gain, current, pricing, and sourcing information with engineering guidance. It also distinguishes verified facts from parameters that still require full-datasheet confirmation, providing a practical basis for initial design and procurement review.
LM258PT - Dual 1.1 MHz Low-Power Op Amp | STMicroelectronics
The STMicroelectronics LM258PT is a dual low-power bipolar operational amplifier packaged in an 8-pin TSSOP. Each of its two independent, internally frequency-compensated amplifiers provides a 100 dB large-signal voltage gain, a 1.1 MHz unity-gain bandwidth, and approximately 500 uA of supply current per amplifier. The device is designed for single-supply operation across a wide voltage range and supports general-purpose signal conditioning. An operational amplifier, or op amp, is a high-gain differential-input amplifier whose inverting and non-inverting inputs produce a single-ended output. Internally frequency-compensated op amps such as the LM258PT are internally stabilized for unity-gain operation without an external compensation network. This makes them suitable for amplifier, buffer, comparator, transducer, and feedback-control circuits where simplicity and low quiescent current are more important than very high bandwidth. Key characteristics include two amplifier circuits in one package, a large DC voltage gain of 100 dB, a 1.1 MHz unity-gain bandwidth, approximately 500 uA of supply current per amplifier, and a typical input bias current of 20 nA. Because the two channels are independent, engineers can use them for cascaded gain stages, differential signal conditioning, active filtering, or separate control and monitoring functions. The internal frequency compensation eliminates the need for external dominant-pole components in most unity-gain applications. The LM258PT is a bipolar-input general-purpose amplifier rather than a rail-to-rail CMOS op amp. Its design is appropriate when a single supply rail is available, input-referred offset is not the dominant system requirement, and operation from a non-rail-to-rail output range is acceptable. Designers must still account for the output-swing limits, common-mode input range, stability requirements, and load capability described by the manufacturer datasheet. Typical uses include low-frequency transducer amplification, sensor signal conditioning, audio preamplification, battery-powered instrumentation, feedback amplifiers in control loops, and general dual-amplifier boards. Its 8-pin TSSOP footprint permits compact surface-mount layouts, while the low 500 uA-per-amplifier supply current helps preserve battery life in portable systems. The main design consideration is stability around the op amp. Place input and output components close to their associated pins, verify capacitive loading against the datasheet stability limits, and avoid driving the output into hard clipping when the input signal exceeds the available output swing. Using the device as a unity-gain buffer requires particular care with capacitive loads because the internal compensation is optimized for a specified load range. This page consolidates manufacturer and distributor information, package details, verified pricing, drop-in alternatives, application guidance, and design notes. It is intended to complement the manufacturer datasheet with selection and implementation context that is not normally presented on a distributor listing page.
LM258QT - Dual 1.1MHz Op Amp | STMicroelectronics
The STMicroelectronics LM258QT is a low-power dual operational amplifier with two independent, internally frequency-compensated amplifiers, a 1.1 MHz unity-gain bandwidth, 100 dB large-signal voltage gain, and an 85 dB common-mode rejection ratio. The device is supplied in an 8-pin DFN package measuring 2 x 2 mm and operates from 3 V to 30 V on a single supply or from ±1.5 V to ±15 V on dual supplies. An operational amplifier is a high-gain analog signal-conditioning IC that compares differential input voltages and amplifies the result. The LM258QT belongs to the operational amplifier hierarchy, where it combines amplifier signal gain, input protection, frequency compensation, and output-current capability in one package. Its two independent channels make it useful for dual-channel signal paths, instrumentation, transducer amplification, and general-purpose analog control. Key features include a 1.1 MHz gain-bandwidth product, 0.6 V/µs slew rate, 2 mV input offset voltage, approximately 20 nA input bias current, and 100 dB DC voltage gain. The low-power architecture is intended for operation across a broad supply-voltage range, while internal frequency compensation avoids the need for external compensation components in standard closed-loop configurations. The two amplifiers are independent, allowing them to amplify different signals or drive separate analog stages. Its 85 dB CMRR helps reject common-mode interference, while its 0.6 V/µs slew rate supports moderate signal slewing requirements. The 1.1 MHz bandwidth is appropriate for low-to-moderate-frequency precision and control circuits rather than high-speed video or RF signal chains. Typical applications include sensor and transducer signal conditioning, industrial control loops, low-frequency measurement instrumentation, audio preamplification, and general-purpose dual-channel amplification. The two-amplifier configuration can reduce component count when a board needs two related analog functions, provided both channels have compatible signal ranges and grounding requirements. Designers should preserve the datasheet-recommended bypass capacitance, verify output swing and load-current limits, and account for input common-mode range near the supply rails. The DFN-8 package also requires careful PCB layout, exposed-pad thermal management, and short feedback and input paths to preserve stability and reduce parasitic effects. This page consolidates verified distributor pricing, package and electrical details, practical application guidance, and pin-compatible replacement information. It also highlights the LM258QT's key engineering trade-offs so purchasing and design decisions can be made against verified source data rather than generic operational-amplifier assumptions.
LM2900D - Quad Norton Operational Amplifier | Texas Instruments
The Texas Instruments LM2900D is a quad, high-gain, frequency-compensated Norton operational amplifier in a 14-pin SOIC (D) package. The device contains four independent amplifier sections designed for single-supply or split-supply operation over a wide supply-voltage range. Its Norton input stage provides low input bias current, while the internally compensated architecture simplifies gain-stage implementation in general-purpose signal conditioning. The LM2900D is identified by the verified distributor listing as a standard general-purpose amplifier with four circuits in a 14-SOIC package. A Norton operational amplifier is a current-buffer input operational-amplifier architecture. It differs from the more common voltage-input differential pair by using a translinear input stage that offers low input bias current and good performance with high-impedance sources. This places the LM2900D in the operational-amplifier hierarchy: operational amplifier, amplifier IC, analog IC, and semiconductor. The part is intended for general-purpose analog signal conditioning rather than precision instrumentation or automotive-qualified systems. According to the Texas Instruments LM2900 product page, the LM2900 family consists of four independent, high-gain frequency-compensated Norton operational amplifiers designed to operate from a single supply over a wide range of voltages. The product description also identifies large output-voltage swing, output short-circuit protection, internal frequency compensation, and low input bias current as important characteristics. These features make the device suitable for buffering, voltage amplification, signal conditioning, and general feedback-control circuits. The LM2900D can be used with a single positive supply or with split supplies. In single-supply designs, the input and output signal levels must remain within the amplifier's common-mode and output-swing limits. The LM2900 family is internally frequency compensated, so the feedback network establishes the closed-loop gain without requiring a separate compensation capacitor in ordinary applications. The 14-pin SOIC package provides a conventional surface-mount footprint and a practical temperature range for industrial and consumer equipment. Typical uses include transducer-signal conditioning, sensor interfaces, audio preamplification, low-current feedback amplifiers, and general analog control loops. Because the verified data does not provide detailed electrical limits, bandwidth, noise, slew rate, or exact input/output range, those parameters should be confirmed in the manufacturer datasheet before final design release. The verified distributor listings show current purchasing channels, but they do not provide a reliable standardized price table in the supplied data. This page combines the verified manufacturer and distributor identity for LM2900D with package information, sourcing links, comparison structure, and practical selection guidance. It is intended to help engineers identify the correct 14-SOIC Norton amplifier while avoiding unsupported parameter assumptions. Confirm the latest ordering information, electrical limits, lead time, and lifecycle status with Texas Instruments or an authorized distributor before production commitment.
LM2900N - Quad 2.5MHz Norton Operational Amplifier | TI
The Texas Instruments LM2900N is a quad, high-gain, frequency-compensated Norton operational amplifier with four independent amplifiers in a 14-pin PDIP package. Its headline specifications include a 2.5 MHz gain-bandwidth product, 20 V/µs slew rate, 4.5 V to 32 V single-supply operation, and ±2.2 V to ±16 V dual-supply operation. An operational amplifier is an analog signal-conditioning IC that uses high open-loop gain to amplify the difference between two input voltages. The LM2900 belongs to the Norton-operational-amplifier family, characterized by current-feedback-style input stages. Within the broader electronics hierarchy, it is an analog amplifier IC, then an operational amplifier, then a general-purpose quad amplifier. The LM2900 provides four independent amplifiers, wide bandwidth, large output-voltage swing, short-circuit protection, internal frequency compensation, and low input-bias current. Internal compensation removes the need for external compensation components in ordinary closed-loop operation, simplifying analog boards that need several amplified signals on one supply rail. Its specified 4.5 V to 32 V single-supply range makes it applicable to legacy industrial control, instrumentation, sensor interfaces, audio, and communications equipment. The 20 V/µs slew rate supports faster edge rates than many general-purpose amplifier selections, while the 2.5 MHz bandwidth gives useful signal bandwidth for audio and control applications. The DIP package also supports through-hole assembly and socketed prototypes. When designing around the LM2900N, verify input and output common-mode limits at the selected supply voltage. Account for the input-bias current when driving high-impedance sensors, and use stable feedback networks with resistive isolation where required by the source impedance. The device uses four independent amplifiers, but shared-package power and ground connections still require careful layout. This product record combines the verified Texas Instruments family description, distributor package information, ordering details, and cross-reference findings. It also distinguishes electrically similar ordering variants from verified pin-compatible replacements and identifies application guidance that is not presented as a manufacturer reference design.
LM2902D - Quad 26V 1.2MHz Op Amp | Texas Instruments
The Texas Instruments LM2902D is a general-purpose quad operational amplifier built with four independent amplifiers, a 26 V maximum supply rating, 1.2 MHz typical gain-bandwidth product, and 2 mV typical input offset voltage in a 14-pin SOIC package. It supports single-supply or split-supply operation and is designed for instrumentation, buffering, amplification, and general analog signal-chain applications. An operational amplifier is a voltage-gain amplifier that uses negative feedback to control gain, bandwidth, input impedance, and output behavior. The quad LM2902 combines four amplifiers in one integrated circuit, reducing board area compared with four separate single or dual amplifier packages. Its general-purpose architecture belongs to the operational-amplifier, analog-amplifier, and semiconductor hierarchy and is widely used where inexpensive, robust signal conditioning is more important than precision or high speed. Key characteristics include four independent amplifier channels, push-pull output capability, a 1.2 MHz typical gain-bandwidth product, and 2 mV typical offset voltage. The 26 V maximum supply rating provides compatibility with common industrial voltage ranges. According to the Texas Instruments LM2902 product page, the device is a quad, 26 V, 1.2 MHz, 2 mV-offset operational amplifier. The distributor listing identifies the LM2902D orderable package as 14-SOIC. The internal architecture is frequency compensated and intended to operate from a single supply or split supply over a wide voltage range. Each amplifier can be used independently, while the common package provides four channels for instrumentation, sensor interfaces, active filters, voltage followers, and signal-conditioning blocks. The device should be selected against the complete input/output voltage, common-mode range, output-current, noise, and thermal requirements of the target circuit. Typical applications include industrial measurement, transducer interfaces, audio and control circuits, low-frequency active filters, sensor amplifiers, and general-purpose analog signal conditioning. Because it is a general-purpose amplifier, the LM2902D is most appropriate when system cost, supply tolerance, and availability matter more than very low offset, rail-to-rail operation, or high-frequency precision. The primary design consideration is supply and signal-range verification. Confirm that every input and output remains within the device's specified operating limits under load, temperature, and supply variation. Decoupling capacitors should be placed close to the supply pins, and each amplifier channel requires appropriate feedback and biasing. PCB creepage, grounding, output loading, and decoupling should be checked during layout. This page combines verified manufacturer and distributor information, drop-in replacement guidance, package comparison data, and practical design notes to help engineers evaluate the LM2902D for new designs and service replacements.
LM2902M - Quad 26 V 1.2 MHz Operational Amplifier | onsemi
onsemi LM2902M is a quad operational amplifier containing four independent, internally compensated high-gain amplifiers in a 14-pin SOIC package. The verified product data identifies it as a standard general-purpose amplifier with a 26 V maximum supply, 1.2 MHz gain-bandwidth product, and typical input offset voltage of 2 mV. It is designed for cost-sensitive analog signal-conditioning circuits that require more than one amplifier in a compact surface-mount package. An operational amplifier is an amplifier IC that uses high open-loop gain and negative feedback to control gain accurately. A quad device integrates four amplifiers, reducing package count and simplifying layouts requiring several channels. The LM2902 family belongs to the operational-amplifier hierarchy and supports common analog functions such as signal amplification, buffering, active filtering, comparisons, transducers, and low-frequency closed-loop control. The key headline characteristics are four amplifier circuits, a 26 V supply rating, 1.2 MHz gain-bandwidth product, 2 mV typical offset voltage, and a 14-pin SOIC package. Internal frequency compensation makes each channel suitable for many unity-gain or moderate-gain applications without an external compensation network. On-chip capacitors in each amplifier support stable operation as a general-purpose voltage-feedback amplifier. The architecture follows the classic high-voltage, internally compensated operational-amplifier approach. Four independent amplifiers share one monolithic substrate but do not share internal signal paths. This allows the same device to implement four separate channels, such as a dual-sensor front end or two complete analog-processing chains. The verified data does not provide exact input bias current, output-current capability, slew rate, or common-mode limits, so those specifications require confirmation from the selected manufacturer's datasheet. Typical uses include industrial sensor interfaces, low-frequency active filters, audio preamplifier stages, process-control modules, instrumentation, and general buffer or gain stages. The quad organization is particularly useful when four similar analog functions must fit on a PCB. Actual circuit suitability depends on supply voltage, source impedance, load impedance, signal frequency, output swing, stability, and thermal conditions. For PCB design, place the device so sensitive analog inputs remain short and route outputs away from switching nodes and high-current paths. Bypass each supply connection near the package with suitable decoupling, maintain a common ground reference, and verify unused-channel inputs are biased so they do not float. The SOIC package also requires a thermal strategy when nearby circuitry drives substantial channel dissipation. This page consolidates the verified distributor and manufacturer product information, identifies where identical MPNs come from different manufacturers, and separates confirmed LM2902M characteristics from parameters that still require manufacturer-specific datasheet review before design release.
LM2902N - Quad 26V 1MHz Op Amp | Texas Instruments
The Texas Instruments LM2902N is a quad, general-purpose operational amplifier in a 14-pin DIP package, with four independent amplifiers per device. The verified source data identifies it as a 26 V maximum supply part with 1 MHz gain-bandwidth behavior, making it suitable for low-cost signal conditioning, instrumentation, and control circuits. The LM2902N combines independent high-gain stages with internally compensated operation from a single supply, while the DIP package supports through-hole assembly and conventional prototype or repair workflows. An operational amplifier is an analog integrated circuit that uses differential input and feedback to control an output voltage. In the broader electronics hierarchy, an op amp belongs to the amplifier-IC family, performs closed-loop signal amplification, and commonly supports filtering, buffering, level shifting, sensing, and control applications. A quad package provides four amplifiers in one IC, reducing component count while preserving separate signal paths where independent channels are useful. The verified product information specifically describes the LM2902-N as a quad 26 V, 1 MHz operational amplifier. The LM2902 family is associated with wide single-supply operation, internally frequency-compensated amplifiers, and general-purpose analog designs. These characteristics are useful when a board needs four amplifier channels with moderate bandwidth rather than a high-speed precision device. Because the available data does not provide the complete electrical tables, detailed input-bias-current, output-swing, noise, and common-mode specifications must be verified in the manufacturer datasheet before production release. Typical uses include sensor conditioning, low-frequency active filters, industrial control loops, audio preamplifier stages, and general-purpose analog signal paths. The 14-pin DIP outline is appropriate when the design uses a through-hole footprint or a manually assembled educational or industrial prototype. Designers should confirm the exact pinout, supply limits, common-mode range, output drive, and stability requirements for the intended operating point rather than relying only on the family-level description. A key design consideration is decoupling: place the supply bypass capacitor close to the device power pins and provide a stable, low-impedance return path. Input and feedback components should be arranged to minimize parasitic pickup and unwanted oscillation. This page distinguishes verified LM2902-N facts from unspecified parameters, making it a practical starting point for procurement and engineering review. The LM2902N combines four channels, a 26 V supply class, and a 1 MHz operating-speed class in a through-hole 14-pin DIP. This combination supports cost-sensitive analog designs where external compensation, rail-to-rail operation, or high bandwidth is not required.
LM2903BIDR - Dual 36V Open-Collector Comparator | Texas Instruments
The Texas Instruments LM2903BIDR is a dual industrial-grade differential comparator with two independent channels, a maximum supply rating of 36 V, open-collector outputs, and a 1 µs response time. It is supplied in an 8-pin SOIC (D) package and is specified for operation from -40 °C to +125 °C. The B-version family also provides a low 0.37 mV input offset, 3.5 nA input bias current, and 200 µA supply current per comparator. A comparator is an analog integrated circuit that determines whether one input voltage is above or below another and switches its output when the differential input crosses a threshold. In the broader semiconductor hierarchy, a comparator belongs to the amplifier and comparator IC family rather than an operational amplifier. Open-collector outputs are useful when multiple devices must share a wired bus or when an external pull-up resistor selects the logic voltage independently of the comparator supply. The LM2903BIDR supports single- or dual-supply operation, allowing its input and output signals to be referenced around ground in control, sensing, and protection circuits. Its industrial temperature range makes it suitable for equipment operating beyond consumer-temperature limits. The two channels are independent, so one device can perform two threshold functions while sharing a package, although output pull-up components and supply decoupling remain external. Verified distributor and manufacturer results identify the device as a standard, general-purpose, rail-to-rail-input comparator with open-collector outputs and an 8-SOIC footprint. Texas Instruments describes the B-version as a next-generation member of the LM393 and LM2903 families, emphasizing lower offset, lower bias current, lower supply current, faster response, wider supply capability, and improved ESD robustness. Typical applications include DC overvoltage monitoring, industrial sensor thresholds, battery-powered indication, window comparators, and relay or alarm activation. Because an open-collector output does not actively drive a high voltage, every application must provide a suitable pull-up resistor and account for its sink-current limit. The collector voltage and supply limits should be checked against the manufacturer datasheet before designing to absolute maximum conditions. For PCB design, place input resistors close to the relevant pins, decouple the supply close to the device, and route high-impedance input traces away from switching nodes. Where open-collector outputs drive cables or long PCB traces, use a strong pull-up and consider a buffer if additional noise immunity or edge control is required. This page combines verified manufacturer and distributor details with engineering guidance for selecting, sourcing, and replacing the component.
LM2903D - Dual Open-Collector Comparator | Texas Instruments
The Texas Instruments LM2903D is a dual differential analog comparator with two independent comparator channels, an operating supply range of 2 V to 36 V, a response time of 300 ns, and an 8-pin SOIC package. Each channel provides open-collector output behavior for level translation, relay driving, and wired-AND logic functions. The device is specified for operation from -40 °C to +125 °C according to the available manufacturer comparison data. An analog comparator is an integrated circuit that compares two input voltages and produces a logic-level output indicating which input is higher. The LM2903D belongs to the comparator hierarchy within analog and mixed-signal semiconductors, providing a simple alternative to an operational amplifier configured as a comparator. Its two channels operate independently, allowing one package to implement two threshold decisions or to control complementary functions in a single circuit. The open-collector outputs are a defining electrical feature. Each output transistor can pull its output low, but it cannot actively drive the output high, so an external pull-up resistor is required. Multiple open-collector outputs can share one pull-up to create a wired-AND arrangement. This architecture also provides a useful form of output isolation while remaining compatible with standard 5 V and 3.3 V digital logic levels when the pull-up rail is selected appropriately. The 2 V to 36 V supply capability allows operation from low-voltage analog systems through conventional industrial control rails. Its 300 ns response time supports applications where decisions must be made faster than typical slow comparators but where nanosecond-level precision is unnecessary. The operating temperature range covers industrial environments, although production designs should still verify temperature-dependent input offset, output-current, and propagation-delay behavior using the selected manufacturer's complete datasheet. Typical uses include industrial sensor conditioning, battery monitoring, overvoltage detection, window or level comparators, relay and solenoid interfaces, and digital control systems that require open-collector outputs. The SOIC-8 package is also appropriate for through-hole-style PCB assembly and manual rework, although SOIC-8 is larger than modern comparator packages such as SOT-23 and MSOP-8 variants. When designing with the LM2903D, always place the input and pull-up networks close to their associated pins, and account for input common-mode limits at the selected supply voltage. A pull-up resistor is not optional because the open-collector output cannot source current. Reviewing the voltage drop across the pull-up and the output transistor's current rating is essential when several outputs share the same node. This page consolidates verified distributor listings, manufacturer references, pin-compatible alternatives, package details, and practical circuit guidance. It also distinguishes directly interchangeable devices from higher-speed or higher-precision alternatives whose electrical behavior may require different design assumptions.
LM2903N - Dual Voltage Comparator, Open-Collector, 8-DIP | TI/STMicro/onsemi
The LM2903N is a dual-channel low-offset voltage comparator supplied in an industry-standard 8-pin PDIP (DIP-8) through-hole package. It integrates two independent precision comparators with 2.0 mV typical input offset voltage, an open-collector output stage capable of swinging to the negative rail (ground-sense at single supply), and operates from a 2 V to 36 V single supply or ±1 V to ±18 V dual supply rail. The output transistor sinks up to 16 mA typical (6 mA minimum over temperature), making the part suitable for directly driving low-power relays, LEDs, and logic interfaces. A voltage comparator is an analog building block that compares two input voltages and produces a binary digital output; when the non-inverting input exceeds the inverting input, the output switches state. The LM2903N belongs to the LM393/LM2903 family - a long-standing industry standard introduced for low-power single-supply sensing, and it sits in the hierarchy: comparator -> analog comparator -> signal conditioning IC -> integrated circuit. Its open-collector architecture requires an external pull-up resistor (typically 10 kohm to VCC), which lets multiple comparators be wire-ORed together and lets the output pull to a different rail than the supply voltage. Key specifications include a 1.3 us typical response time at 5 V/2 mA, a 2.5 mV maximum input offset voltage (LM2903 grade), an input bias current of 25 nA typical, and ESD clamps on the inputs that tolerate human-body-model discharge. The device operates across the automotive-industrial -40 C to +125 C range (LM2903N suffix N designates the PDIP-8 package, not the temp grade). The LM2903's architecture uses a PNP input stage that gives the inputs an exceptionally wide common-mode range that includes the negative rail (ground), which is why single-supply ground-referenced sensing is its dominant application. The open-collector NPN output stage isolates the comparator logic from the load voltage; only the pull-up rail sets the high-level output. Typical applications include battery monitoring in 12 V/24 V automotive and industrial systems (window detectors, under-voltage cutoff), zero-crossing detectors for mains interfaces when paired with an optocoupler, line-receiver / level-shift interfaces between high-voltage analog and low-voltage logic, threshold alarms and signal-conditioning front-ends, and oscillator / relaxation-oscillator circuits. When designing with the LM2903N, observe one trade-off: open-collector outputs use a pull-up resistor that adds RC delay to the rising edge - at 10 kohm with 100 pF of trace capacitance, rise time is about 1 us. For high-speed logic interfaces downstream, size the pull-up conservatively or use a discrete or integrated push-pull comparator when sub-microsecond edge rates are needed.
LM2903P - Dual Differential Comparator, 30 V, PDIP-8 | Texas Instruments
The Texas Instruments LM2903P is a dual differential comparator with open-collector, rail-to-rail outputs, supplied in an 8-pin PDIP package. The device contains two independent voltage comparators designed for general-purpose signal conditioning, threshold detection, and simple control applications. The verified distributor and manufacturer data identifies the LM2903 as a dual differential comparator intended for operation from a single supply or dual supplies, with a maximum supply voltage rating of up to 38 V for the B-version family and a listed operating supply range of 2 V minimum for comparison devices in the same family. A comparator is an analog integrated circuit that compares two input voltages and produces a digital logic result. The LM2903 family belongs to the broader comparator and analog signal-conditioning hierarchy, where open-collector outputs provide flexible interface options for pull-up resistors, relay drivers, lamp circuits, and low-voltage digital logic. Its differential inputs allow one signal to be monitored against a reference or another input, making the device suitable for window detection, current sensing, sensor thresholding, and industrial control circuits. The LM2903P uses two independent comparators, with output transistors capable of sinking current into an external pull-up network. The verified data identifies the output style as open-collector and rail-to-rail, while the family description confirms two independent voltage comparators and operation from a single power supply over a wide voltage range. The LM2903P is supplied through a tube package in the verified distributor result, making it appropriate for through-hole production and prototype boards rather than compact surface-mount assemblies. Typical uses include monitoring a control voltage, detecting an overvoltage or undervoltage condition, converting an analog sensor threshold into a logic event, and driving an alert or shutdown input. Because an open-collector output requires an external pull-up resistor, the output voltage is defined by the pull-up supply and resistor rather than by the comparator alone. Designers should also verify input common-mode limits, output sink current, supply-current requirements, and propagation delay for the exact operating conditions. The principal design consideration is that the LM2903P is a through-hole PDIP-8 comparator, not a low-power modern micropower comparator. Its application circuit must respect the device's supply voltage, input voltage, common-mode range, output pull-up arrangement, and maximum output current. This page combines the verified manufacturer and distributor information with practical application guidance and same-family replacement context for engineers evaluating an LM2903P design.
LM2904BIDR - Dual 36V 1.2MHz Op Amp | SOIC-10 | TI
The Texas Instruments LM2904BIDR is an industry-standard dual operational amplifier in an 8-pin SOIC package, delivering 1.2 MHz unity-gain bandwidth and a wide 3 V to 36 V supply range with single-supply operation. It is the next-generation 'B' revision of the legacy LM2904, providing tighter DC accuracy (lower input offset voltage), lower noise, and a 1.2 MHz bandwidth upgrade versus the original 700 kHz device, while remaining in the industry-standard 8-pin SOIC footprint used by all LM358 / LM2904 variants. Each channel is a bipolar voltage-frontier amplifier with internal EMI/RFI filtering and ESD protection on the inputs, and the device operates over the automotive -40C to +125C temperature range. An operational amplifier (op amp) is a high-gain DC-coupled differential amplifier whose output voltage is amplified by an external feedback network to perform amplification, filtering, and signal conditioning. A dual op amp integrates two ICs into a single package and is the same circuit-level topology (LDO) integrated with a higher-level power-supply chain and ultimately a semiconductor device, while dual op amps specifically serve as a low-side companion building block used in many sensor, instrumentation, and power-management signal chains. Key features include 1.2 MHz gain-bandwidth product, 0.5 mV typical (3 mV maximum) input offset voltage, 45 V/us (typical) slew rate, 25 nA input bias current, and an output swing that includes both rails. The device operates on a single supply from 3 V up to 36 V (or dual +/-1.5 V to +/-18 V). It is internally compensated for unity-gain stability and includes short-circuit protection on the output, making it suitable for direct drive of low-impedance loads in industrial and automotive environments. The LM2904BIDR uses a bipolar process with a PNP input stage that supports input common-mode voltages down to ground (and up to VCC - 1.5 V), enabling true single-supply operation from a 5 V or 12 V rail. The dual-channel architecture allows one IC to implement two independent gain stages - commonly a transimpedance amplifier and a buffer, or two channels of a differential sensor front-end - saving PCB area, cost, and complexity versus using two single-channel op amps. Typical applications include transducer interfaces (load cells, strain gauges, pressure and flow sensors), low-side current sensing in motor drives and battery management, active filters and integrators for instrumentation, comparator-like threshold detection, and general-purpose signal conditioning on 12 V / 24 V industrial and automotive buses. The wide supply range and automotive-grade temperature rating make it drop-in compatible with virtually every legacy LM288 / LM358 / LM2904 design. When designing with this device, ensure the input common-mode voltage remains within the linear range (GND to VCC - 1.5 V). For single-supply designs, AC-couple the input or bias the network to mid-supply. Decouple the supply pin with a 1 uF / 100 nF parallel pair within 10 mm of the IC, and avoid driving capacitive loads greater than 1 nF directly - add a series isolation resistor if needed. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving you a complete engineering perspective in one page.
LM2904M - Dual 26V 700kHz Op Amp | Texas Instruments
The Texas Instruments LM2904M is a dual, general-purpose operational amplifier with a 26 V supply rating, 700 kHz gain-bandwidth product, and an 8-SOIC package. According to the Texas Instruments LM2904 product page, the device is intended for low-power analog signal-processing systems where two amplifiers are useful in a single package. The verified distributor listing identifies LM2904M as a standard two-circuit amplifier in an 8-SOIC package, and the Mouser result specifies the operating-temperature range as -40 °C to 85 °C. An operational amplifier is an analog integrated circuit that uses feedback to amplify the difference between its non-inverting and inverting inputs. The LM2904M belongs to the broader operational-amplifier, analog-amplifier, and semiconductor hierarchies. In practical circuits, each internal amplifier can serve as an inverting amplifier, non-inverting amplifier, comparator, buffer, or integrator when operated with suitable external components and supply voltages. The 26 V supply rating provides compatibility with conventional industrial and analog signal ranges, while the 700 kHz gain-bandwidth product supports low-to-moderate-frequency signal amplification. The dual configuration reduces package count when a circuit needs two amplifier channels. Its general-purpose designation indicates broad applicability rather than a specialized low-noise, high-speed, precision, or automotive-only function. The LM2904M uses an 8-SOIC surface-mount package, corresponding to the soic-8 package library key. The verified results do not provide a complete electrical specification table in the supplied excerpts, so detailed parameters such as input offset voltage, input bias current, slew rate, output-current capability, common-mode range, quiescent current, and noise values are marked as data needed rather than estimated. Typical applications include low-frequency analog signal conditioning, instrumentation interfaces, sensor buffers, audio preamplifier stages, and general dual-amplifier circuits. The dual channel can also be used for active filtering or control loops where two matched functional amplifier sections are useful. Because the available information is general-purpose and distributor-oriented, the designer should verify operating-point limits, loading, stability, and temperature margin against the manufacturer datasheet before release. For PCB implementation, place bypass capacitors close to the supply pins and route sensitive input and feedback traces away from switching nodes and high-current paths. Confirm the exact pin orientation and electrical limits before assembly. This page combines verified manufacturer and distributor references with explicitly marked data gaps rather than inventing missing specifications.
LM2904N - Dual 1 MHz 26 V Op Amp | Texas Instruments
Texas Instruments LM2904N is a dual, internally frequency-compensated operational amplifier with two independent amplifiers, a 26 V maximum supply designation, and a 1 MHz gain-bandwidth product. It is supplied in an 8-pin PDIP package. The device is designed for general-purpose signal conditioning from industrial control to audio and sensor interfaces. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. Internally compensated LM2904N amplifiers are voltage-amplifier building blocks within the operational-amplifier, analog IC, and semiconductor hierarchies. Their differential inputs support filtering, buffering, summing, comparison, and feedback-control functions without requiring an external compensation network. The verified product information identifies two amplifiers, single-supply or split-supply use, low power drain, and a common-mode input range extending to ground or VEE. Its internally frequency-compensated architecture simplifies closed-loop design, while the dual configuration places two matched-function amplifiers in one package. However, the supplied data does not state output-current capability, input-offset voltage, input-bias current, slew rate, noise density, or operating-temperature limits. A key design consideration is supply configuration. Although the official TI product-page snippet specifies a 26 V product family designation, engineers must consult the exact manufacturer datasheet before setting rail voltage, input common-mode limits, output swing, and load current. Decoupling capacitance, input impedance, feedback topology, output loading, and thermal dissipation also remain datasheet- and layout-dependent. Typical uses include two-channel sensor conditioning, low-frequency active filters, audio preamplification, comparator-style signal detection with suitable saturation limits, control-loop buffering, and general dual-rail analog signal processing. The 1 MHz bandwidth is most appropriate for low-to-moderate-frequency signals rather than high-speed precision instrumentation. This data page combines verified manufacturer and distributor facts, pin-compatible replacement screening, and practical engineering guidance. It deliberately leaves unverified electrical values marked for completion rather than inferring specifications from related dual-amplifier families.
LM2904P - Dual 26V 700kHz Op Amp | Texas Instruments
The Texas Instruments LM2904P is a dual, general-purpose operational amplifier designed for single- or dual-supply operation up to 26 V, with a 700 kHz gain-bandwidth product and two amplifiers per package. The LM2904P is supplied in an 8-pin PDIP package, making it suitable for through-hole industrial, instrumentation, and control designs. According to the Texas Instruments product page, the device is a standard dual operational amplifier rather than a low-noise or precision amplifier. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. In a closed-loop configuration, external feedback components define the gain, bandwidth, filtering, and signal behavior. The LM2904P belongs to the broader hierarchy of operational amplifier, analog amplifier, and semiconductor, while its dual configuration saves board area by placing two amplifiers in one package. The verified manufacturer information identifies a maximum 26 V supply-related range and 700 kHz performance. The package is 8-PDIP. Texas Instruments describes the LM2904 as an industry-standard dual operational amplifier family, but the supplied verified data does not include a complete electrical parameter table. Consequently, input offset voltage, input bias current, output current, noise, common-mode range, slew rate, operating temperature, and exact electrical limits are marked as data needed rather than inferred. LM2904P circuits are commonly considered for sensor amplification, buffered analog signals, low-frequency active filters, and general-purpose control loops. Because it is a standard dual amplifier in a through-hole package, it is especially useful for prototypes, educational boards, legacy equipment, and industrial control systems where DIP packaging simplifies manual assembly and inspection. The second amplifier can mirror the first stage, provide filtering, buffer an output, or implement another independent channel. Designers should verify supply polarity, input common-mode limits, output swing, stability with the selected load, and capacitor values against the full manufacturer datasheet before production use. Decoupling capacitors should be placed close to the supply pins, and feedback components should be kept compact to reduce parasitic capacitance. If low-noise, rail-to-rail input/output, high-frequency, or automotive-qualified performance is required, a different amplifier family should be selected after reviewing the complete electrical data. This page consolidates the verified Texas Instruments product description, distributor identification, and package information with engineering guidance, comparison points, and procurement-oriented details for LM2904P users.
