ISO1211DR

ISO1211DR - 24V-60V Isolated Digital Input | Texas Instruments (Tape & Reel)

The Texas Instruments ISO1211DR is a single-channel isolated digital input receiver designed for 24V to 60V digital input modules, with an 8-pin SOIC (D) package. It supports 9V to 300V DC and AC input designs when used with external resistors, while providing accurate current limiting for low-power dissipation. The device targets PLC digital input interfaces and industrial control systems. An isolated digital input receiver converts field-side voltage states into a logic signal presented to a controller or other electronics. The ISO1211 belongs to the isolated-interface IC hierarchy and replaces conventional optocoupler input stages with an integrated receiver designed for high-side industrial input conditions. Its isolation function protects control-side circuitry from field-side electrical conditions while transferring the input state. Key verified features include compliance with IEC 61131-2 Type 1, 2, and 3 characteristics for 24V isolated digital inputs, bipolar input support, broken-wire detection, and an operating temperature range from -40C to +125C. The current limit is specified as 2.2mA to 2.47mA for Type 3 designs. The SOIC package provides eight terminals and is identified by TI as package code D. The ISO1211DR is intended for programmable logic controllers, motor-control systems, grid infrastructure, and other industrial equipment with isolated digital inputs. External resistors set the supported field-input voltage range, so the final input network must be selected according to the intended DC or AC voltage and the applicable IEC 61131-2 input type. The receiver architecture allows the field interface to be designed without reproducing a discrete optocoupler circuit. Designers should verify the complete pinout, isolation requirements, resistor values, voltage ratings, and input thresholds against the manufacturer datasheet before production. The verified product page identifies ISO1211DR as an 8-pin SOIC (D) device rated from -40C to +125C. Its principal engineering value is integration of a field-input receiver into a compact, application-specific interface for industrial control equipment. This page consolidates verified manufacturer and distributor information, IEC 61131-2 compatibility information, package data, application context, and design guidance. It does not infer unreported electrical values, invent pricing, or substitute a different package simply to create an alternative.

ISO121BG - ±10V Precision Isolation Amplifier 3500Vrms | Texas Instruments
ISO121BG

ISO121BG - ±10V Precision Isolation Amplifier 3500Vrms | Texas Instruments

The Texas Instruments ISO121BG is a precision isolation amplifier with ±10V bipolar input range, 3500Vrms isolation rating, and 0.01% maximum nonlinearity, housed in a 16-pin CDIP_SB (JVD) through-hole package. It is part of TI's Burr-Brown isolation amplifier family and uses duty-cycle modulation-demodulation across a 2pF differential capacitive barrier. An isolation amplifier is a specialized differential amplifier that provides galvanic isolation between its input and output stages, breaking ground loops and protecting downstream circuitry from high-voltage transients. Within the broader signal-chain hierarchy, isolation amplifiers sit between instrumentation amplifiers (which amplify small differential signals) and digital isolators (which only pass logic levels). They combine precision analog front-end conditioning with reinforced isolation, making them essential in systems where analog signals must cross a safety barrier. Key features of the ISO121BG include user control of the carrier frequency for synchronization, 100% partial discharge testing, high common-mode rejection (IMR) at 60Hz, and bipolar operation across its ±10V input range. The part is rated for -55C to +125C operation and is specified for the 16-pin side-brazed ceramic DIP (CDIP_SB) package designed for high-voltage isolation applications. The device uses duty-cycle modulation to encode the analog input as a digital pulse train that crosses a 2pF capacitive isolation barrier; the output side demodulates this pulse train back to an analog voltage. Because modulation is digital, the barrier's analog imperfections (nonlinearity, drift, aging) do not corrupt signal integrity, yielding 0.01% max nonlinearity and stable gain over time. Typical applications include precision voltage sensing in motor drives, shunt-based current sensing in high-voltage systems, isolated process-control signal acquisition, medical patient monitoring with reinforced isolation, and ground-loop elimination in industrial 4-20mA loops. Designers choose the ISO121BG when the application demands 3500Vrms isolation (vs. the 1500Vrms ISO120) and excellent DC accuracy at industrial temperatures. When designing with the ISO121BG, pay attention to PCB layout: keep input and output grounds physically separated by the package isolation barrier, use star-grounding at the power supplies, and place the external oscillator capacitor as close to the OSC pin as possible to minimize carrier-frequency drift and IMR degradation.

ISO121G - ±10V Precision Isolated Amplifier | Texas Instruments
ISO121G

ISO121G - ±10V Precision Isolated Amplifier | Texas Instruments

The Texas Instruments ISO121G is a precision low-cost isolated amplifier with a ±10 V input range, one amplifier circuit, and a 16-pin CDIP package. According to the Texas Instruments product page, it is designed for precision voltage sensing, while the manufacturer datasheet identifies low nonlinearity, bipolar operation, and duty-cycle modulation-demodulation as central characteristics. Its isolation barrier transfers the signal digitally rather than relying on analog leakage through the barrier, helping preserve signal integrity in electrically noisy or high-voltage environments. An isolated amplifier is a signal-conditioning component that transfers a measured voltage across an electrically isolated barrier while preventing direct conductive coupling between the input and output domains. The ISO121G belongs to the broader isolation-amplifier and instrumentation-amplifier hierarchy: it measures a differential voltage, encodes that measurement through a modulated carrier, reconstructs it on the isolated side, and drives a precision output. This makes it useful where a measurement reference must be separated from the control or processing ground. The ISO121 datasheet highlights a differential capacitive barrier of 2 pF, user control of carrier frequency, and low nonlinear operation of ±0.01% maximum. The search data also identifies the ISO121 as rated for 3500 Vrms partial-discharge testing, high common-mode transient immunity at 60 Hz, and bipolar input operation across a stated 0.3-wide range in the source summary. Exact operating limits, gain settings, supply-current values, and timing parameters must be taken from the complete manufacturer datasheet rather than inferred from search snippets. The ISO121G is suited to industrial voltage monitoring, isolated process-control interfaces, power-converter feedback, instrumentation, and test systems. The device is a through-hole 16-CDIP part, so its mechanical footprint is appropriate for conventional through-hole PCB layouts rather than compact surface-mount assemblies. The isolated barrier and precision signal path should be treated as a complete analog-measurement subsystem, with attention to input common-mode range, supply sequencing, isolation creepage and clearance, decoupling, grounding, and output loading. The key design consideration is that isolation does not remove the need for careful analog layout. Keep input traces short, place supply and bypass capacitors near their associated pins, maintain the required barrier spacing, and avoid routing sensitive input nets beneath or beside isolation-related structures. Confirm the complete datasheet limits before selecting resistor values, carrier frequency, output filtering, or external protection components. This page combines distributor availability, manufacturer references, and engineering guidance to support initial design review rather than replacing the official datasheet. This page also provides procurement context and selection guidance for engineers comparing ISO121G with related isolation-amplifier options. Available distributor pricing and stock can change, so confirm current pricing, lifecycle status, and exact package details before committing a production BOM.

It supports bipolar ±10 V operation, uses a fixed unity-gain configuration, and requires no external components for operation. An isolation amplifier is a precision analog signal-conditioning component that transfers a voltage signal across a galvanic isolation barrier while electrically separating input-side and output-side circuits. In the signal-chain hierarchy, the ISO122 belongs to the isolation-amplifier family, instrument-amplifier class, analog front end, and broader semiconductor category. Its built-in matched capacitive barrier supports high-voltage isolation and reduces the need for external isolation-network design. The ISO122 uses duty-cycle modulation and demodulation to transmit the input signal across a differential capacitive barrier. Key verified specifications include 1500 Vrms high-voltage breakdown rating, 50 kHz bandwidth, 0.020% maximum nonlinearity, and 200 V/°C input-offset-voltage drift. Its power-supply range is 4.5 V to 18 V, while stated quiescent currents are 5 mA on VS1 and ±5.5 mA on VS2. The device is intended for precision analog measurement and signal conditioning where isolated sensing improves safety or reduces ground-loop effects. The fixed unity-gain architecture simplifies implementation, and the manufacturer states that no external components are required for basic operation. The available package options include plastic DIP and surface-mount configurations, with ISO122JP identified by distributors as an 8-PDIP device. Typical uses include isolated current measurement, industrial sensor interfaces, medical monitoring, power-conversion feedback, and laboratory instrumentation. The 50 kHz bandwidth supports signals above very-low-frequency sensing but is not intended for high-speed data acquisition. The main design consideration is ensuring the isolation barrier, creepage, clearance, supply bypassing, and input/output grounding meet the safety requirements of the target installation. This page combines verified manufacturer specifications, distributor product information, and cross-reference findings. Cross-reference results identify related ISO124 devices, but the supplied evidence does not establish a verified pin-to-pin drop-in replacement for ISO122JP; alternatives are therefore limited and clearly qualified.

The device is supplied in an 8-pin plastic DIP package, identified by distributor listings as 8-PDIP or a 16-DIP mechanical outline with 8 leads. The isolation amplifier uses duty-cycle modulation and demodulation, transmitting the analog signal digitally across a 2 pF differential capacitive barrier. This architecture supports galvanic isolation between the input and output sides while preserving the behavior of a precision isolated measurement channel. According to the Texas Instruments product description and the distributor records verified on 2026-10-30, ISO122JPE4 is designed for cost-sensitive industrial instrumentation, isolated sensor interfaces, and measurement systems where a compact 8-pin DIP package and reinforced isolation are useful. The verified listing describes the device as a precision low-cost isolation amplifier operating from 4.5 V to 18 V, with 50 mV input range, 1.5 kV isolation, and 50 kHz bandwidth. Its isolated signal path can help reduce ground-loop errors and protect low-voltage sensor circuitry when the measured equipment operates at a different potential. The 8-pin DIP outline is suitable for conventional through-hole PCB layouts and prototype instrumentation, although designers should verify creepage, clearance, and isolation requirements against their final board construction. The ISO122JPE4 is distinct from the related ISO122P and ISO122JP variants, so package suffix, electrical limits, temperature range, and production status should be checked before substituting. This page synthesizes the verified manufacturer and distributor information with practical selection guidance and explicitly identifies unavailable electrical details rather than estimating them.

ISO122JU - 50kHz Precision Isolation Amplifier | Texas Instruments
ISO122JU

ISO122JU - 50kHz Precision Isolation Amplifier | Texas Instruments

The Texas Instruments ISO122JU is a precision, low-cost isolation amplifier with one isolation channel, a 50 kHz signal bandwidth, 0.020% maximum nonlinearity, and an 8-pin SOIC package. It uses a 4.5 V to 18 V power-supply range and fixed unity-gain operation. The isolation amplifier’s specified input-side quiescent current is 5 mA, while its output-side supply current is ±5.5 mA. These characteristics make ISO122JU suitable for industrial measurement, current sensing, data acquisition, and power-conversion feedback where galvanic isolation and accurate signal transfer are required. An isolation amplifier is an analog signal-conditioning device that transfers a voltage signal across a galvanic-isolated barrier while preventing a conductive electrical connection between input and output circuits. The isolation amplifier hierarchy includes isolation amplifier, signal conditioner, analog interface, and semiconductor. ISO122JU places matched 1 pF capacitors inside the plastic package and transmits a duty-cycle-modulated representation of the input signal across the barrier. This architecture supports high-voltage isolation and reduces the need for external signal-conditioning components. The principal ISO122 features include 0.020% maximum nonlinearity, 50 kHz signal bandwidth, and 200 V/°C input-offset-voltage drift. Its fixed unity-gain configuration simplifies circuit design because no external gain-setting network is required. The manufacturer states that no external components are required for operation. Its isolation-oriented construction is particularly useful when measuring voltage across a high-side shunt or when a control, instrumentation, or protection domain must remain electrically separated from a hazardous or high-voltage domain. The device is available in an 8-pin SOIC package, identified by the JU ordering code. The verified distributor listing describes ISO122JU as a one-circuit, 8-SOIC isolation amplifier. Its power supplies must meet the stated 4.5 V to 18 V range, and the circuit designer should account for independent supply requirements on the input and output sides. The listed quiescent-current specifications are 5 mA on VS1 and ±5.5 mA on VS2, making supply budgeting important when several isolation channels share a regulated rail. Typical applications include isolated current measurement in power converters, motor-control feedback, industrial sensor interfaces, medical-equipment signal acquisition, and high-voltage process monitoring. The fixed unity gain and 50 kHz bandwidth simplify many measurement paths, but applications requiring substantially wider bandwidth, higher accuracy, adjustable gain, or different isolation ratings should be compared against other isolation amplifiers before committing to the ISO122JU. For PCB layout, treat the isolation barrier as a controlled high-voltage region rather than an ordinary signal path. Confirm the package pinout against the manufacturer datasheet, observe the creepage and clearance requirements applicable to the installation, and avoid placing unprotected copper or test pads across the isolation boundary. The component is an analog interface device rather than a power semiconductor, so SOA data is not applicable. This page consolidates the verified manufacturer specifications, distributor package identification, official datasheet link, and practical selection considerations for engineers evaluating the ISO122JU.

ISO122JU/1K - 50kHz Isolation Amp | Texas Instruments
ISO122JU/1K

ISO122JU/1K - 50kHz Isolation Amp | Texas Instruments

The Texas Instruments ISO122JU/1K is a precision, low-cost isolation amplifier with a ±10 V bipolar input range, 50 kHz signal bandwidth, 1500 Vrms working isolation voltage, and a fixed unity-gain configuration, housed in an 8-pin SOIC package. The device is designed for voltage-sensing systems that require signal transfer across a high-voltage barrier without a direct galvanic connection. An isolation amplifier is a specialized signal-conditioning IC that combines input amplification, electrical isolation, and output amplification in one package. In the broader semiconductor hierarchy, it belongs to the analog amplifier family and the industrial signal-chain category. Its capacitive barrier separates the input side from the output side, allowing measured voltages to be transferred safely while minimizing common-mode interference and ground-potential errors. The ISO122JU/1K offers maximum nonlinearity of 0.020%, input offset-voltage drift of 200 V/°C, and a nominal 2 pF differential capacitive barrier. Its fixed unity-gain architecture simplifies implementation by avoiding an external feedback network. The 50 kHz bandwidth supports rapidly changing process-control and instrumentation signals, although it is not intended for high-frequency communications waveforms. Operationally, the ISO122 uses a novel duty-cycle modulation and demodulation technique to transmit the input signal digitally across the differential capacitive barrier. This architecture supports bipolar input operation and fixed unity gain while maintaining a compact 8-pin SOIC footprint. The verified manufacturer listing identifies 5 mA quiescent current on VS1 and ±5.5 mA on VS2, with a 4.5 V to 18 V power-supply range. Typical uses include industrial process-control loops, motor and solenoid current monitoring, power-supply feedback isolation, high-voltage sensor interfaces, data-acquisition systems, and isolated communications front ends. The 1500 Vrms working isolation rating and high-frequency common-mode rejection are particularly useful when a sensor ground differs substantially from the measurement-system ground. Designers should verify the complete power-supply arrangement, input common-mode range, isolation boundary, and output-load requirements against the manufacturer datasheet. The input and output grounds must remain isolated from one another; joining them would bypass the principal safety function. Decoupling should be placed directly at the supply pins, while the analog input path should minimize leakage and high-impedance contamination around the sensitive input node. This product data combines verified manufacturer specifications, distributor availability, package information, and explicitly qualified replacement analysis. It also distinguishes genuine drop-in alternatives from merely similar isolation amplifiers, helping engineers avoid substitutions that change pin functions, supply requirements, signal bandwidth, or isolation architecture.

ISO122JUE4 - 50 kHz Precision Isolation Amp | Texas Instruments
ISO122JUE4

ISO122JUE4 - 50 kHz Precision Isolation Amp | Texas Instruments

Texas Instruments ISO122JUE4 is a precision, low-cost isolation amplifier with 0.020% maximum nonlinearity, 50 kHz signal bandwidth, and 200 V/°C input-offset-voltage drift in an 8-pin SOIC package. It accepts a single-ended analog input, provides galvanic isolation between the input and output domains, and operates from a 4.5 V to 18 V supply. The device uses duty-cycle modulation and demodulation to transmit the signal digitally across a 2 pF differential capacitive barrier. An isolation amplifier is a specialized amplifier that transfers a low-level analog measurement across a galvanic-isolated barrier while minimizing electrical coupling between the sensed side and the output side. Within the signal-chain hierarchy, the ISO122 belongs to the amplifier family and provides signal conditioning plus reinforced isolation for industrial, medical, and test equipment. Its digital transmission across the capacitive barrier reduces sensitivity to barrier-characteristic changes and improves high-frequency transient immunity. Key features include a maximum nonlinearity of 0.020%, a 50 kHz signal bandwidth, and a 200 V/°C input-offset-voltage drift specification. The power-supply range is 4.5 V to 18 V, with a reported quiescent current of 5 mA on VS1 and ±5.5 mA on VS2. The single-ended input architecture simplifies measurement interfaces where a differential source is not available, while the 8-SOIC format supports compact surface-mount construction. Internally, the ISO122 converts the analog input into a duty-cycle-modulated signal and demodulates it on the output side. The signal therefore crosses the isolation barrier digitally rather than as a continuously varying analog voltage. The verified product information identifies a 2 pF differential capacitive barrier, and a Partstack listing reports a maximum common-mode voltage of 1500 V. Designers must still verify the complete isolation rating, package details, creepage, clearance, and certification requirements against the current manufacturer documentation before applying the device to a safety-critical interface. Typical applications include industrial sensor isolation, current-shunt measurement, high-voltage sensing interfaces, test and measurement equipment, and isolated process-control inputs. The 50 kHz bandwidth is appropriate for relatively low-frequency process signals rather than high-speed data acquisition. The 4.5 V to 18 V supply range also permits operation from common laboratory and industrial rails, although each isolated side must be powered independently according to the manufacturer application guidance. When designing around the ISO122JUE4, treat the barrier capacitance, input common-mode range, supply arrangement, and isolation return path as system-level constraints. Confirm that the selected protection network does not introduce unacceptable input impedance or gain error, and place the supply-return and output-reference layout according to the manufacturer guidance. The 50 kHz bandwidth and 0.020% maximum nonlinearity should be included in the complete error budget rather than treating the isolation amplifier as an ideal gain stage.

ISO122JUG4 - 50 kHz Isolation Amplifier | Texas Instruments
ISO122JUG4

ISO122JUG4 - 50 kHz Isolation Amplifier | Texas Instruments

Texas Instruments ISO122JUG4 is a single-circuit isolation amplifier with a verified bandwidth of 50 kHz, supplied in an 8-lead SOIC package measuring 0.295 inches, or 7.50 mm, in width. The device belongs to the instrumentation-amplifier and signal-conditioning family, where an isolation barrier separates a measurement input from the electronics that process, transmit, or display the resulting signal. Its 50 kHz bandwidth makes it relevant to industrial measurement, current sensing, power-conversion feedback, and other analog signal paths that require galvanic isolation. An isolation amplifier is an amplifier with two electrically separated sides: an input side connected to the sensed signal and an output side connected to the host electronics. This separation can help protect sensitive measurement circuitry from high common-mode voltages and reduce the need for a direct ground connection between different portions of an industrial system. Within the broader semiconductor hierarchy, ISO122JUG4 is an analog integrated circuit, an isolation amplifier, an instrumentation signal-conditioning component, and a power-management-adjacent interface device for protected measurement systems. The verified product information identifies the ISO122JUG4 as a 50 kHz isolation amplifier with one circuit in an 8-SOIC package. The 8-lead surface-mount format supports compact PCB layouts while providing separate input-side and output-side connections. The verified distributor records also identify the device as a Texas Instruments isolation amplifier. Detailed electrical characteristics such as supply voltage, isolation rating, gain configuration, input impedance, output offset, common-mode rejection, and temperature range were not included in the supplied data and therefore must be confirmed against the manufacturer datasheet before design release. A 50 kHz bandwidth is appropriate for many industrial analog signals, including current-transformer outputs, voltage-derived measurements, and feedback loops requiring isolation. The bandwidth should be compared with the required signal bandwidth and phase margin; a signal that approaches the device's upper frequency limit may require additional consideration because the total system response includes the isolation amplifier, sensing network, input and output filters, and load. No gain or filter values are inferred here because the provided sources do not specify them. Typical uses include isolated current measurement in power supplies, industrial process-control interfaces, motor-drive sensing, medical-instrument signal acquisition, and communication equipment requiring an isolation barrier. In these applications, the device can interface a floating sensor to a grounded controller while preserving the functional separation between high-energy and low-energy circuits. The system's isolation requirements, creepage, clearance, and reinforced-insulation targets must still be evaluated independently of signal bandwidth. The most important design step is to obtain and review the official ISO122 datasheet before assigning the supply rails, external gain components, input network, output filter, and isolation layout. Because the supplied sources establish the device type, 50 kHz bandwidth, single-circuit configuration, and 8-SOIC package, but do not provide a complete electrical table or pin mapping, no unsupported pin names or voltage ratings are asserted in this record. This page consolidates verified distributor pricing, package information, source links, and practical application context into one engineering-oriented reference. It also distinguishes what is confirmed from what remains datasheet-dependent, helping engineers evaluate ISO122JUG4 without confusing similar isolation products or unrelated digital isolators with this analog isolation amplifier.

ISO122P

ISO122P - Precision 50kHz Isolation Amplifier | Texas Instruments

The Texas Instruments ISO122P is a precision, lowest-cost isolation amplifier with 0.020% maximum nonlinearity, 50 kHz signal bandwidth, and 200 V/°C input offset-voltage drift, supplied in an 8-pin plastic DIP package. It transfers low-frequency analog signals across a high-voltage isolation barrier while preserving signal integrity through duty-cycle modulation and demodulation. An isolation amplifier is a signal-conditioning amplifier that electrically separates an input-side circuit from an output-side circuit while passing the measured signal. The ISO122P belongs to the isolation-amplifier, analog-amplifier, signal-conditioning, and power-management protection categories. Its isolation barrier supports designs where input and output grounds must remain separated for safety, fault containment, or prevention of ground-loop currents. The principal verified features include 1500 Vrms high-voltage breakdown testing, fixed unity-gain configuration, bipolar operation from ±10 V, and compatibility with supply voltages from 4.5 V to 18 V. The low-side VS1 supply draws approximately 5 mA, while the VS2 supply uses approximately ±5.5 mA. Its 50 kHz bandwidth supports relatively fast process-control and instrumentation signals while the 0.020% maximum nonlinearity emphasizes accurate analog reproduction. Internally, the ISO122P transmits the analog information by duty-cycle modulation and reconstructs it through synchronous demodulation. The barrier carries a differential capacitor signal rather than requiring a continuous analog signal to cross the isolation boundary. Digital modulation helps the barrier characteristics have less influence on signal integrity. The device uses a fixed unity-gain architecture, simplifying external gain-setting design. Typical applications include industrial process-control loops, current-shunt measurements, sensor interfaces, data acquisition, power-inverter feedback, and isolated analog signal conditioning. In each case, the design must maintain adequate supply headroom, observe the specified isolation and layout requirements, and account for the 50 kHz bandwidth before selecting external filtering. A key design consideration is that the DIP package is not interchangeable with the separate 28-lead surface-mount ISO122 option without a PCB footprint change. Keep high-voltage and low-voltage copper areas separated, place bypass capacitors close to the supply pins, and treat the isolation barrier and input common-mode limits as layout constraints rather than ordinary analog routing concerns. This page combines the manufacturer specifications, verified distributor availability information, package details, and application guidance to support component selection and PCB design. Pricing and stock must be checked against current distributor listings as of 2026-10-22 rather than inferred from generic marketplace records.

ISO122PG4 - 50 kHz Precision Isolation Amplifier | Texas Instruments
ISO122PG4

ISO122PG4 - 50 kHz Precision Isolation Amplifier | Texas Instruments

The Texas Instruments ISO122PG4 is a precision isolation amplifier with a 50 kHz signal bandwidth, one isolated signal channel, and an 8-pin PDIP (PG) through-hole package. It moves an analog signal across a 2 pF differential capacitive isolation barrier using a duty-cycle modulation/demodulation technique, so the barrier never carries the analog signal itself and its characteristics do not degrade signal integrity. The device is supplied from the ISO122 family in the RoHS-compliant PDIP-8 outline, which makes it convenient for through-hole industrial, instrumentation, and test-and-measurement designs. An isolation amplifier is a specialized amplifier-and-barrier combination used to transfer a low-level analog measurement across a galvanic isolation boundary. In the hierarchy it sits under precision amplifier -> instrumentation amplifier -> isolation amplifier -> signal-chain IC, and it exists because standard op amps cannot survive the ground-potential differences and safety barriers found in industrial control, medical-style monitoring, and mains-referenced measurement systems. Typical isolation barriers must withstand kilovolt-level transients while passing microvolt-to-volt signals with predictable gain and low output offset. Key characteristics of the ISO122PG4 include its 50 kHz bandwidth, single-channel (one circuit) isolation topology, differential analog input, differential analog output, and DIP-8 through-hole mechanical format. Because the modulation scheme is digital in nature, the isolation barrier capacitance is used only for current injection and clock transfer, which removes the gain error and linearity shift that analog barrier-based designs suffer with temperature and aging. The RoHS-compliant construction and PDIP outline suit long-life industrial equipment where a surface-mount-only part would complicate rework. Architecturally, the ISO122 divides into a high-side input stage, a barrier region containing the 2 pF differential capacitors, and an output reconstruction stage. The receiver demodulates the duty-cycle-modulated carrier back into a differential analog output so downstream ADC front ends can be driven differentially, halving the sensitivity to common-mode noise pickup on the wiring between the amplifier and the converter. Typical applications include industrial sensor interface and data acquisition modules, isolated PLC and DCS input channels, medical-style patient-monitoring front ends, high-voltage power-converter feedback isolation, and laboratory test equipment where a high-side shunt measurement must be transferred safely to the low-voltage control domain. In each of these, the ISO122PG4 acts as the analog front end of the isolated measurement chain. One design consideration worth noting: when placing this part in a through-hole design, keep the input-side ground and output-side ground planes completely separate and provide the decoupling capacitors called for in the TI datasheet directly at the supply pins. Isolation is only as good as the creepage and clearance of the layout around the barrier. This page consolidates distributor pricing, same-family drop-in options, package details, and practical design guidance for the ISO122PG4 so engineers can evaluate the part quickly, compare it against sibling TI isolation amplifiers, and source it without re-reading multiple distributor listings.

ISO122U - Precision Isolated Amplifier, 50kHz, SOIC-8 | TI

The Texas Instruments ISO122U is a precision low-cost isolation amplifier with 0.020% maximum nonlinearity, 50 kHz signal bandwidth, 200 V/°C input-offset-voltage drift, and an 8-pin SOIC package. Its input range is ±10 V, its high-voltage isolation rating is 1500 Vrms, and it requires no external components for operation. An isolation amplifier is a differential amplifier whose input and output domains are electrically separated by a reinforced isolation barrier. This category belongs to the precision amplifier hierarchy, which includes instrumentation amplifiers, operational amplifiers, buffer amplifiers, and signal-conditioning ICs. ISO122U is intended to transfer measured analog signals across high potential differences while limiting ground current and protecting equipment on opposite sides of the barrier. Key features include 100% high-voltage breakdown testing, fixed unity gain, a 4.5 V to 18 V power-supply range, and low supply demand. The verified data specifies approximately 5 mA quiescent current on VS1 and ±5.5 mA on VS2. These characteristics suit compact, cost-sensitive industrial systems where accurate voltage sensing and galvanic isolation are more important than high bandwidth. The isolation amplifier converts a differential input voltage into a ground-referenced output on the secondary side. Its 0.020% maximum nonlinearity limits gain-related error, while the 50 kHz bandwidth supports relatively fast control or measurement loops. The 200 V/°C offset-drift specification helps control error as temperature changes, although system-level accuracy still depends on input and reference components. Typical uses include motor-drive current sensing, industrial sensor interfaces, power-inverter feedback, isolated voltage measurement, and high-side sensing where the source can be several hundred volts above the controller ground. The isolation barrier also helps prevent ground faults and switching transients from corrupting measurements or endangering downstream circuitry. A critical design consideration is to preserve the isolation barrier by keeping input-side and output-side copper, components, and external networks physically separated according to the manufacturer layout guidance. Decoupling and grounding should remain independent on both sides; joining them defeats the purpose of galvanic isolation. Supply voltage and signal limits should also be checked at temperature rather than only at room temperature. This page combines verified manufacturer specifications, distributor availability and pricing information, explicit data gaps, and cross-reference results. Because the supplied evidence does not establish five verified pin-to-pin alternatives, the alternatives array is omitted rather than padded with unverified package or reel-code variants.

Texas Instruments ISO122U/1K is a precision voltage-sensing isolation amplifier with ±10 V input range, 50 kHz signal bandwidth, and 1500 Vrms working isolation voltage in an 8-pin SOIC package. The device uses duty-cycle modulation and demodulation to transfer the input signal across a 2 pF differential capacitive barrier, supporting high-voltage isolation without a transformer or isolation optocoupler. An isolation amplifier is a precision analog signal-conditioning IC that electrically separates an input measurement from its output and ground domains. Within the product hierarchy, the ISO122U/1K is an isolation amplifier, a voltage-sensing signal conditioner, an analog amplifier IC, and ultimately a semiconductor. Its capacitive isolation barrier helps protect personnel and downstream circuitry when monitoring high-voltage process-control signals. Key specifications include a maximum nonlinearity of 0.020%, input-offset voltage drift of 200 V/°C, and signal bandwidth of 50 kHz. The power supply range is 4.5 V to 18 V, while the verified manufacturer data identifies approximately ±10 V bipolar operation. These characteristics make the ISO122U/1K appropriate for precision voltage sensing, current-shunt measurement, industrial instrumentation, and isolated data acquisition. Internally, the ISO122U/1K transmits information digitally across the differential capacitive isolation barrier through duty-cycle modulation and demodulation. Although the information crosses the barrier digitally, the external signal remains an analog voltage presented by the isolation amplifier. The 2 pF barrier and 1500 Vrms working isolation rating distinguish it from conventional non-isolated operational amplifiers. Typical applications include industrial process-control loops, motor-drive monitoring, power-supply feedback isolation, high-voltage sensor interfaces, and isolated measurement systems. The 50 kHz bandwidth is suitable for relatively slow control and instrumentation signals rather than high-frequency communications. In a shunt-measurement circuit, the amplifier can preserve ground separation between a high-side or floating sensor and the controller ground. Designers should place input and output bypassing capacitors close to their respective supply pins, maintain the isolation barrier clear of conductive PCB features, and verify creepage, clearance, and working-voltage requirements against the completed system. The 50 mV input-offset maximum and 0.020% nonlinearity should also be included in the end-to-end measurement error budget. This page combines verified manufacturer specifications, distributor availability and pricing references, package information, design guidance, and traceable source links. It distinguishes documented electrical limits from application-level calculations and avoids treating merely similar isolation products as guaranteed drop-in replacements.

ISO124P - 8-Pin DIP Isolation Amplifier, 1.5kV | Texas Instruments

The Texas Instruments ISO124P is a precision, low-cost isolation amplifier housed in an 8-pin PDIP package, providing 1.5 kVrms galvanic isolation between input and output through a duty-cycle modulation scheme across matched 1 pF internal capacitive barriers. Key headline specifications are 0.010% maximum nonlinearity, 50 kHz small-signal bandwidth, and a 200 uV/°C maximum input offset drift, with a bipolar ±10 V input range that accepts signals symmetrically around ground. An isolation amplifier is a specialized analog IC that transmits an analog signal across a galvanic isolation barrier - typically required for safety, ground-loop elimination, or high common-mode voltage rejection - while preserving DC accuracy and bandwidth. The ISO124P belongs to the instrumentation amplifier family and is further categorized as an isolation amplifier, sitting within the broader analog signal-chain and data-acquisition hierarchies. It is one of the lowest-cost precision isolation solutions in the industry and is widely used where optical, transformer, or digital isolators are unsuitable for the analog accuracy required. The device features ±4.5 V to ±18 V dual supply operation on both sides of the barrier, ±5 mA quiescent current on V_S1 and ±5.5 mA on V_S2, and a fixed unity-gain configuration that eliminates external gain-setting resistors and removes a common source of drift. Its high common-mode rejection (140 dB typical) makes it tolerant of large ground potential differences and switching transients on industrial buses, while the capacitive digital modulation scheme avoids the LED aging and linearity limitations of opto-isolated solutions. Typical applications include motor control current sensing, biomedical signal acquisition with patient-isolated inputs, industrial process-control analog front-ends with 4-20 mA loop isolation, and power-supply feedback isolation in high-side current monitors. The PDIP-8 form factor is well-suited to through-hole designs and is preferred where mechanical robustness and ease of prototyping outweigh the area advantage of surface-mount variants. When designing with this part, ensure the supplies on each side of the barrier are truly isolated and that bypass capacitors (typically 0.1 uF plus 1 uF) are placed close to each supply pin to handle the high-frequency switching of the modulator. Because the signal path includes a 500 kHz modulator running continuously, allow adequate ground-plane stitching on both isolated sections to avoid contaminating the rest of the analog chain. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet. It targets engineers searching for a complete engineering reference on ISO124P selection, replacement, and PCB integration.

The Texas Instruments ISO124U is a precision isolation amplifier for bipolar analog-signal isolation, featuring a ±10 V input range, 50 kHz signal bandwidth, and maximum nonlinearity of 0.010%. It is packaged in an 8-pin SOIC (DVA) and uses separate supply domains to transfer signals across a reinforced isolation barrier. An isolation amplifier is a signal-conditioning semiconductor that transfers an analog input voltage while maintaining galvanic separation between the input-side and output-side circuitry. The isolation amplifier category belongs to the broader instrumentation-amplifier and signal-conditioning hierarchy, where accuracy, noise rejection, common-mode immunity, and safe voltage separation are central design requirements. ISO124U is intended to preserve signal integrity while transferring measurements across high-voltage, industrial, or safety-related boundaries. The ISO124U uses a differential capacitive barrier and a duty-cycle modulation-demodulation technique to transmit the signal digitally across the isolation boundary. According to the manufacturer datasheet, this approach prevents barrier characteristics from directly affecting signal integrity and provides strong high-frequency transient immunity. The device supports bipolar operation, a fixed unity-gain configuration, and supply rails from ±4.5 V to ±18 V. Key specifications include 0.010% maximum nonlinearity, 50 kHz signal bandwidth, and input-offset-voltage drift of 200 µV/°C. Quiescent current is ±5 mA on VS1 and ±5.5 mA on VS2. The input-side and output-side supply domains allow the output side to operate at a different voltage reference from the input side, which is useful when measuring signals across high-side or floating power domains. The 8-pin SOIC package also supports conventional surface-mount assembly. Typical uses include isolated current and voltage measurement, industrial process-control acquisition, power-converter feedback isolation, data-acquisition systems, instrumentation front ends, and high-side sensing. The isolation barrier allows the sensing circuit to remain electrically separate from the controlled equipment, provided the PCB layout, creepage, clearance, decoupling, and barrier requirements follow the manufacturer’s guidance. When designing around ISO124U, separate input-side and output-side ground planes and maintain the required isolation boundary. Keep analog traces short and place input and output bypass capacitors near their respective supply pins. The fixed unity-gain configuration simplifies signal-chain design, while the ±10 V input range and 50 kHz bandwidth limit the design to suitable analog signal levels and frequency content. This page combines verified manufacturer and distributor data, practical application guidance, and verified cross-reference results for ISO124U. It is intended to help engineers evaluate supply requirements, signal bandwidth, isolation placement, package compatibility, and sourcing without relying on unverified generic substitutions.

ISO124U/1K - ±10V Precision Isolation Amplifier | Texas Instruments

The Texas Instruments ISO124U/1K is a precision, low-cost isolation amplifier for sensing bipolar voltages within a ±10-V input range. It uses duty-cycle modulation and demodulation to transmit the measured signal across a 2-pF differential capacitive barrier, providing galvanic isolation between the input and output sides. The device is packaged in an 8-pin SOIC (DVA) package and is designed for measurement and control systems that require signal isolation. An isolation amplifier is a specialized interface amplifier that transfers a low-level input signal while electrically separating the input circuitry from the output circuitry. The isolation barrier prevents ground-potential differences and high-voltage events on one side of the system from corrupting measurements or damaging downstream circuitry. In the power-management hierarchy, the ISO124U/1K belongs to the isolation-amplifier and signal-conditioning IC category, where accurate voltage sensing, galvanic isolation, and compact implementation are the primary design goals. The ISO124U/1K supports a precision isolation-amplifier configuration with fixed unity gain and bipolar operation. According to the Texas Instruments product information, maximum nonlinearity is 0.010%, signal bandwidth is 50 kHz, and input offset-voltage temperature drift is 200 µV/°C. These characteristics make the device suitable for industrial instrumentation, current-voltage sensing, power-conversion feedback, and isolated control or measurement circuits. The device operates from dual supplies in the range of ±4.5 V to ±18 V, allowing it to interface with systems using conventional analog rails. Quiescent current is approximately ±5 mA on VS1 and ±5.5 mA on VS2. The ISO124 family is also characterized by high-voltage isolation testing and a rated isolation barrier of 1500 Vrms, although final working-voltage and safety-limit decisions must be based on the complete system requirements and manufacturer documentation. Typical uses include isolated shunt measurement, inverter and motor-control feedback, power-supply monitoring, test and measurement equipment, and industrial communication interfaces. The 50-kHz bandwidth is sufficient for many control and sensing signals but is not intended for high-frequency waveform capture. The capacitive isolation barrier should be treated as a safety-critical component when it is part of an end-product isolation barrier. When designing around the ISO124U/1K, provide local decoupling close to the supply pins and respect the input common-mode range. The input voltage range is limited to ±10 V, so larger process signals require attenuation or protection. Confirm the output swing, supply polarity, isolation rating, and system creepage and clearance requirements before releasing a production design. This page combines manufacturer specifications, distributor availability information, and same-footprint alternatives for engineering selection.

ISO124U/1KG4 - 50kHz Isolation Amplifier | Texas Instruments

The Texas Instruments ISO124U/1KG4 is a precision isolation amplifier with a 50 kHz signal bandwidth, maximum nonlinearity of 0.010%, and input offset-voltage drift of 200 µV/°C, housed in an 8-pin SOIC package. The device supports dual supply rails from ±4.5 V to ±18 V and draws 5 mA from VS1 and 5.5 mA from VS2. An isolation amplifier is a precision signal-conditioning IC used to transfer an analog voltage across a high-impedance barrier while preventing direct electrical conduction between the input and output domains. The ISO124 belongs to the broader isolation-amplifier, analog-signal-conditioning, interface-IC, and semiconductor hierarchies. Its isolation barrier supports instrumentation systems that require signal transfer without a conductive path between the measured circuit and the readout electronics. The ISO124 uses duty-cycle modulation and demodulation to transmit the signal digitally across a differential capacitive barrier. Because the information is represented by modulation rather than analog voltage amplitude, barrier characteristics do not directly determine signal-integrity performance. Key features include 0.010% maximum nonlinearity, 50 kHz bandwidth, and 200 µV/°C offset-voltage drift. The dual-supply range of ±4.5 V to ±18 V permits operation from low-voltage analog systems through higher-voltage industrial rails. Quiescent current is 5 mA on VS1 and 5.5 mA on VS2, making the device suitable for precision measurement circuits where supply efficiency and signal accuracy must be balanced. The 8-pin SOIC footprint supports conventional surface-mount assembly and compact analog boards. Typical uses include isolated current sensing, industrial process-control inputs, sensor-interface circuits, power-conversion feedback isolation, and test-and-measurement front ends. The 50 kHz bandwidth accommodates signals that vary more quickly than static voltage references while retaining the accuracy expected from precision isolation stages. When laying out an ISO124U/1KG4 circuit, place supply bypassing close to the device and maintain the isolation boundary required by the system architecture. Confirm input common-mode range, supply sequencing, and barrier-layout recommendations in the manufacturer datasheet. Treat the 50 kHz bandwidth and 0.010% nonlinearity as separate design limits because a signal within the bandwidth can still incur meaningful gain or linearity error. This page consolidates the manufacturer specifications, practical application guidance, drop-in family options, and engineering trade-offs needed to evaluate the ISO124U/1KG4 before incorporating it into a precision isolated-interface design.

ISO1410BDW - 500kbps Isolated RS-485/RS-422 | Texas Instruments

The Texas Instruments ISO1410BDW is an EMC-protected, galvanically isolated RS-485/RS-422 transceiver rated for data rates up to 500 kbps and half-duplex communication. The device is packaged in a 16-pin wide-body SOIC (DW) package and operates from -40°C to +125°C. Its 5 kVrms isolation rating and integrated digital isolation separate the bus-side interface from the logic-side circuitry, helping protect sensitive host electronics from ground-potential differences and industrial transients. The transceiver supports both RS-485 and RS-422 applications and is intended for factory automation, industrial control, building automation, and other electrically noisy environments. An isolated RS-485/RS-422 transceiver combines differential bus signaling, galvanic isolation, and logic-side interfacing. RS-485 is commonly used for multipoint, half-duplex industrial buses, while RS-422 provides differential signaling for communication between two endpoints. In the power-management and interface hierarchy, this device is a digital isolator combined with a physical-layer line transceiver rather than a protocol converter or a general-purpose logic IC. Its capacitive-isolation architecture separates data across the isolation barrier while the transceiver drives or receives differential bus signals. Key features include support for signaling rates up to 500 kbps, half-duplex operation, EMC-focused bus-pin protection, 5 kVrms isolation, and operation across the full -40°C to +125°C temperature range. The 16-pin DW package provides a wide-body surface-mount footprint with sufficient lead spacing for industrial assembly workflows. The availability of a half-duplex architecture allows a controller to share a communication channel for command and response traffic when the bus is idle. The ISO1410 product family is positioned between lower-rate and very-high-speed isolated serial interfaces. The supplied TI family description identifies ISO141x devices as supporting up to 500 kbps, while ISO143x devices support up to 12 Mbps and ISO145x devices up to 50 Mbps. This distinction matters when selecting a replacement because signal rate, bus timing, and isolation implementation must match the original design intent. The ISO1410BDW is therefore most appropriate where 500 kbps operation and EMC resilience are sufficient but higher throughput is unnecessary. Typical uses include industrial RS-485 buses, programmable logic controller communication, factory equipment interfaces, industrial sensor gateways, building-control networks, and isolated host connections. In these systems, the transceiver converts logic-level data into differential RS-485 or RS-422 signals, while its isolation barrier reduces the effect of unequal ground potentials between a controller and field equipment. A termination strategy, biasing network, protective earth connection, and correctly designed transceiver interface remain necessary for reliable operation. A key design consideration is that isolation does not remove the need for careful bus implementation. The logic and bus-side supply domains should be decoupled appropriately, and the differential pair should be routed as a controlled-impedance network with minimized stub lengths. Designers should also verify the required data rate, cable length, termination values, grounding strategy, and transient requirements against the complete system rather than treating the IC as a complete surge-protection solution. This product page combines verified manufacturer and distributor information, package and ordering data, comparison criteria, and application-oriented engineering guidance. It also distinguishes documented drop-in options from related family members and identifies where additional verification is required before replacing an installed ISO1410BDW.

It provides one transceiver per package and is intended for industrial communication links exposed to electrostatic discharge, electrical fast transients, and other electromagnetic disturbances. An isolated RS-485/RS-422 transceiver is an interface IC that converts logic-level signals into differential bus signals and receives differential bus signals back into logic-level outputs. Galvanic isolation places a reinforced isolation barrier between the bus-facing side and the logic side of the device. Within the product hierarchy, the ISO1410DW is a differential line transceiver, an interface IC, and a semiconductor designed for industrial networking and control systems. The ISO1410DW's principal verified features include a maximum signaling rate of 500 Kbps, 5 kVrms isolation, half-duplex operation, RS-485 and RS-422 support, and robust EMC protection. Its 16-pin DW SOIC package provides sufficient pin count for the isolated transceiver interface, supply connections, bus terminals, and enable-related functions. The wide -40°C to +125°C temperature range makes it suitable for industrial equipment subjected to extended thermal conditions. Texas Instruments describes the ISO14xx family as galvanically isolated differential line transceivers for TIA/EIA RS-485 and RS-422 applications. These noise-immune devices are designed for harsh industrial environments, and their bus pins are intended to withstand high levels of IEC electrostatic-discharge and electrical-fast-transient events. The manufacturer also provides the ISO1410DWEVM evaluation module for evaluating the ISO1410 in its 16-pin wide-body SOIC package. Typical uses include isolated industrial bus links, factory automation equipment, building-control gateways, industrial sensors, and communication interfaces located at a significant ground-potential difference from the host controller. In these systems, the transceiver provides the physical-layer connection between a logic-side controller and a differential RS-485 or RS-422 bus. Half-duplex operation allows a shared pair of conductors to carry data in both directions, but bus direction must be managed by the host interface. Designers should confirm the complete pinout, isolation requirements, bus termination strategy, fail-safe behavior, and external interface voltage levels against the manufacturer datasheet before layout. A 16-pin wide-body SOIC footprint should not be mixed with a narrow-body SOIC footprint, and the isolation barrier placement should follow the manufacturer's recommended layout and creepage guidance. This page consolidates verified manufacturer and distributor information for ISO1410DW, including commercial availability, package details, application guidance, and a conservative drop-in replacement assessment. It also separates confirmed specifications from fields that require confirmation from the complete datasheet, helping engineers shorten component research without obscuring uncertainty.

The device supports single-side powered isolation, industrial temperature operation from -40°C to +125°C, and a robust EMC protection network for long-distance differential data links. Its isolated transceiver architecture places a galvanic barrier between the bus-facing interface and the logic-side interface, helping protect host circuitry from ground-potential differences and electrical transients. An isolated RS-485/RS-422 transceiver is a communication interface that combines differential line drivers, differential receivers, and electrical isolation within one integrated circuit. In the broader hierarchy, it belongs to interface ICs and bus transceivers. RS-485 supports multipoint, half-duplex buses in many installations, while RS-422 commonly supports point-to-point, full-duplex links. The ISO1412BDW supports both standards and provides 500-kbps operation for industrial communication, factory automation, building controls, and equipment networks. Key features include 500-kbps signaling speed, full-duplex operation, 5-kVrms isolation, EMC protection, and operation from -40°C to +125°C.

The ISO1412BDW is identified as RoHS compliant by distributor data, and its operating-temperature range supports use across demanding commercial and industrial environments. Exact supply-voltage, receiver-threshold, propagation-delay, and bus-loading limits should be confirmed in the manufacturer datasheet. The ISO1412BDW is designed for bidirectional differential data transfer across an isolation barrier. Full-duplex capability permits separate transmit and receive paths, which is useful when a system cannot switch a shared half-duplex bus. The integrated protection and isolation functions reduce the amount of external surge and isolation circuitry required, but correct layout, decoupling, bus termination, and common-mode considerations remain essential for reliable field communication. Typical uses include industrial PLC and factory-automation links, isolated instrumentation, building-automation equipment, long-reach RS-485 or RS-422 nodes, and industrial gateways that must bridge a noisy bus to a host controller. The 500-kbps rate is suitable for supervisory data, configuration traffic, and moderate-speed industrial messages rather than high-bandwidth streaming. Design the isolation barrier and bus interface on the PCB with the manufacturer's isolation and layout guidance. Keep bus-side and logic-side copper, components, and ground systems separated, place decoupling capacitors at the appropriate supply pins, and apply termination only where signal-integrity analysis requires it. The isolation rating and EMC claims must be evaluated for the final enclosure, cable, grounding, and surge environment. This page consolidates the verified manufacturer and distributor information for the ISO1412BDW, distinguishes confirmed characteristics from parameters requiring datasheet review, and provides application and selection guidance that is not available from a distributor listing alone.

Typical uses include industrial PLC and factory-automation links, isolated instrumentation, building-automation equipment, long-reach RS-485 or RS-422 nodes, and industrial gateways that must bridge a noisy bus to a host controller. The 500-kbps rate is suitable for supervisory data, configuration traffic, and moderate-speed industrial messages rather than high-bandwidth streaming. Design the isolation barrier and bus interface on the PCB with the manufacturer's isolation and layout guidance. Keep bus-side and logic-side copper, components, and ground systems separated, place decoupling capacitors at the appropriate supply pins, and apply termination only where signal-integrity analysis requires it. The isolation rating and EMC claims must be evaluated for the final enclosure, cable, grounding, and surge environment. This page consolidates the verified manufacturer and distributor information for the ISO1412BDWR, distinguishes confirmed characteristics from parameters requiring datasheet review, and provides application and selection guidance that is not available from a distributor listing alone.
