ISO102B

ISO102B - High-Voltage Isolation Buffer Amplifier | Texas Instruments

The Texas Instruments ISO102B is a low-cost, high-voltage, wide-bandwidth, hermetic-DIP signal isolation buffer amplifier with 1 channel in a 16-pin CDIP (J Package) ceramic package. The device operates from ±10V to ±20V dual supplies and provides up to 70 kHz small-signal bandwidth while delivering a capacitive barrier isolation of 1500 Vrms (continuous), 2500 Vrms (1 s test), and 6000 V peak transient overvoltage protection per UL 544/VDE Class V safety targets. What is an isolation buffer amplifier? An isolation amplifier is an analog front-end device that transfers a small differential signal across a galvanic isolation barrier while rejecting high common-mode voltages between input and output grounds. Inside the ISO102 family, a low-level input stage modulates a carrier that crosses a capacitive barrier; the receiver demodulates and reconstructs the signal. Compared to opto-isolated or transformer-based isolators, the capacitive-barrier design of the ISO102/ISO120 family preserves analog linearity and bandwidth, making the device a fundamental building block in medical, industrial, and process-control signal chains where patient safety or ground-loop protection is mandatory. Key features include 1.4 mV maximum input offset voltage (B grade), low input bias current, a unity-gain buffer input stage, and integrated short-circuit-protected output. The unit delivers 2500 Vrms continuous (1 s test) isolation rating. The hermetic side-brazed ceramic DIP (16-CDIP) package provides a wide operating temperature range and meets the reliability expectations of military, aerospace, and down-hole instrumentation programs. The ISO102B uses a duty-cycle modulation-demodulation topology with a 2pF differential capacitive isolation barrier. Unlike transformer or optocoupler isolators, this capacitive approach delivers excellent common-mode transient immunity (CMTI) and preserves DC accuracy down to sub-Hz frequencies. Internal ±15V regulators on each side of the barrier decouple the barrier from supply noise, allowing clean operation from poorly filtered industrial rails. Typical applications include ECG/EEG patient monitoring front-ends, industrial 4-20 mA loop isolation, motor-drive IGBT gate-driver analog feedback, high-voltage test equipment signal paths, and process-control analog I/O modules. The wide 70 kHz bandwidth supports thermocouple, strain-gauge, and flow-meter signal conditioning where the input signal is several volts above earth ground. When designing with the ISO102B, place decoupling capacitors as close as possible to both the input-side and output-side supply pins (1 µF ceramic minimum), and use a 0.1 µF bypass cap for high-frequency noise. Maintain at least 8 mm of creepage/clearance on the PCB to preserve the 2500 Vrms isolation rating and avoid routing any conductor under the package that would compromise the barrier. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers select a true pin-to-pin equivalent and accelerate design-in.

ISO103

ISO103 - 20kHz Internally Powered Isolation Amp | TI

The Texas Instruments ISO103 is a low-cost, internally powered isolation amplifier with a 20 kHz bandwidth, one amplifier circuit, and a 16-lead CDIP package. Its verified isolation test voltage is 5600 Vpk, while the continuous AC barrier rating is 1500 Vrms. The input signal range extends to +10 V, and the device is described as operating at 20 kHz both for small-signal and full-power bandwidth. An isolation amplifier is a differential amplifier whose input and output domains are electrically separated by a reinforced isolation barrier. In the broader hierarchy, ISO103 belongs to the isolation-amplifier class, then to instrumentation amplifiers, then to analog signal-conditioning ICs and semiconductors. This category transfers low-frequency or low-frequency-plus-audio-band analog information across a high-voltage barrier without requiring a direct electrical connection between the two sides. The principal verified features include internal power, a wide input signal range of +10 V, 20 kHz small-signal bandwidth, and 20 kHz full-power bandwidth. The manufacturer’s datasheet description also identifies the device as a low-cost isolation amplifier. These values position ISO103 for analog isolation, instrumentation, industrial control, and signal-conditioning systems where bandwidth, barrier rating, and a through-hole package are more important than miniature packaging. The 16-CDIP construction is mechanically significant for systems that use conventional through-hole PCB assembly rather than fine-pitch surface-mount parts. A distributor listing identifies ISO103 as a 16-CDIP isolation amplifier, while another listing identifies a 24-CDIP package for a related representation; the target data therefore preserves the target package as 16 leads and flags package-specific verification where the supplied snippets conflict. ISO103 is an analog IC, so a safe-operating-area chart is not applicable. Typical applications include isolated sensor interfaces, industrial process-control signal paths, power-inverter feedback, medical monitoring signal isolation, test and measurement input conditioning, and communication-interface isolation. The 20 kHz bandwidth is suitable for many analog control and measurement signals, but it should not be interpreted as a high-speed digital isolation or RF isolation solution. The 5600 Vpk test voltage and 1500 Vrms continuous AC barrier rating are the verified isolation-related figures available from the supplied data. Designers should confirm the exact pinout, input polarity, supply requirements, gain configuration, isolation limits, and system-level creepage and clearance before layout. The supplied web results identify the device and its major isolation and bandwidth characteristics, but do not provide a complete authoritative electrical table, recommended PCB land pattern, or detailed application circuit. Those values must be taken from the manufacturer datasheet before production release. This page combines the verified product identity, distributor availability information, package references, isolation ratings, bandwidth data, and sourcing URLs. It does not invent missing gain, supply-voltage, input-impedance, output-voltage, or exact pin-function values; those fields remain explicitly marked for data completion.

ISO103B

ISO103B - Internally Powered Isolation Amplifier | Texas Instruments

The Texas Instruments ISO103B is an internally powered isolation amplifier with a 20 kHz bandwidth, 1500 Vrms continuous AC barrier rating, and a 16-CDIP ceramic package. It combines input signal conditioning and galvanic isolation in one device, making it suitable for industrial measurement and control systems. The isolation barrier is specified as 5600 Vpk test voltage, while the wide input signal range supports signals beyond conventional low-level sensor outputs. An isolation amplifier is a type of instrumentation amplifier that transfers a signal across a galvanic barrier while preventing conductive current from flowing between the input and output domains. This protects sensitive measurement equipment from high common-mode voltages, ground faults, and potentially hazardous electrical environments. The ISO103B belongs to the broader signal-chain and isolation-IC hierarchy rather than a conventional non-isolated operational amplifier. Key features include integrated signal and power handling in one double-wide, 0.6-inch side-brazed package; 5600 Vpk test voltage; 1500 Vrms continuous AC barrier rating; and a specified 20 kHz small-signal and full-power bandwidth. The internally powered architecture simplifies system design by reducing the number of external isolation-supply components. The 16-terminal CDIP package is intended for through-hole industrial and laboratory equipment. Technically, the device combines an isolated input stage, isolation barrier, and output amplifier. Its bandwidth limits the fastest transient and signal behavior, while its continuous barrier rating addresses sustained AC isolation rather than only a short-duration production test. Designers must consider the complete isolation path, creepage, clearance, barrier insulation, and the datasheet pinout before applying the part to a high-voltage installation. Typical uses include current and voltage measurement, process-control instrumentation, data acquisition, power-supply feedback isolation, laboratory signal conditioning, and industrial sensor interfaces. The 20 kHz bandwidth is appropriate for many measurement signals but not for high-frequency communications or waveform systems requiring greater bandwidth. A critical design consideration is to preserve the intended isolation barrier and avoid unintended copper bridges or leakage paths. PCB layout, creepage, clearance, input filtering, grounding, and the package’s mechanical orientation must be reviewed against the manufacturer datasheet. This page consolidates verified manufacturer and distributor information, package details, isolation specifications, comparison fields, and practical design guidance to support component selection without fabricating missing electrical values.

ISO1042BQDWRQ1

ISO1042BQDWRQ1 - 5 Mbps Isolated CAN FD Transceiver | Texas Instruments

Texas Instruments ISO1042BQDWRQ1 is a galvanically isolated Controller Area Network transceiver supporting CAN FD data rates up to 5 Mbps and complying with ISO11898-2 (2016). It provides ±70 V DC bus fault protection, a ±30 V common-mode voltage range, and automotive-grade isolation in a 16-pin SOIC package. A CAN transceiver is the physical-layer interface between a CAN controller and the differential CAN bus. It converts logic-level TXD and RXD signals into CAN bus levels and receives bus activity for the controller. Galvanic isolation places a robust communication barrier between the bus-side circuitry and the logic-side circuitry, helping prevent ground-potential differences and high-energy bus faults from propagating into sensitive electronic systems. The ISO1042-Q1 family combines flexible data-rate operation with unusually strong bus fault tolerance. Its ±70 V DC bus fault protection exceeds the transient and fault voltages normally encountered in harsh vehicle environments, while the ±30 V common-mode range supports operation across nodes with significant ground offsets. CAN FD support allows higher payload throughput than classic CAN, helping reduce transfer time when larger data frames are needed. The device is intended for automotive and industrial networks in which robust isolation, high fault tolerance, and deterministic communication are important. Suitable uses include electric-vehicle power electronics, vehicle body controllers, battery-management systems, industrial automation equipment, and isolated diagnostic interfaces. The wide fault range is especially useful in environments where wiring faults, load dump events, or ground shifts can stress connected nodes. PCB layout is critical because the isolation barrier, bus traces, ground separation, and protection network must be implemented according to the manufacturer datasheet. Keep the isolated-side and logic-side copper regions separated, route the CANH and CANL pair as a balanced differential pair, and place bus-side protection components close to the connector. Maintain the specified creepage, clearance, capacitor, and termination arrangements to preserve isolation and communication reliability. This page combines the manufacturer device description, ordering information, verified product links, application guidance, and practical design notes to help engineers evaluate the ISO1042BQDWRQ1 for isolated CAN FD nodes. It also identifies same-footprint family alternatives while clearly separating verified product facts from parameters requiring confirmation in the datasheet.

ISO1042DW

ISO1042DW - 5Mbps Isolated CAN Transceiver | Texas Instruments

The Texas Instruments ISO1042DW is a galvanically isolated CAN transceiver with a 5 Mbps maximum data rate, reinforced isolation, and 16-pin wide-body SOIC (DW) packaging. It supports classic CAN operation up to 1 Mbps and CAN FD operation up to 5 Mbps while meeting the ISO 11898-2:2016 physical-layer standard. The device also provides ±70 V DC bus fault protection and a ±30 V common-mode voltage range. These specifications make it suitable for industrial, transportation, and other electrically noisy installations where a CAN node requires reinforced isolation from its host circuitry. An isolated CAN transceiver is a physical-layer interface device that couples a controller-area-network bus to digital logic while maintaining galvanic isolation between the two sides. In the hierarchy of electronic components, it belongs to the CAN transceiver class, then to wired network interfaces, communications ICs, and ultimately semiconductor devices. Isolation is especially valuable when ground-potential differences, high-energy bus faults, or long external cable runs could otherwise damage a controller or create an unsafe grounding path. The ISO1042DW combines several protective and performance features in one interface. Its 152 ns loop delay supports dependable communication at high CAN FD rates, while ±70 V DC bus fault protection tolerates severe DC faults on the bus side. The ±30 V common-mode range improves tolerance to voltage differences between the transceiver and other nodes. The device supports a 1.8 V to 5.5 V supply range and is offered in a 16-pin wide-body SOIC package for surface-mount assembly. Technically, the ISO1042 is divided into logic-side and bus-side functional regions by its reinforced isolation barrier. CAN TX and RX signals pass through this barrier to the bus interface, while bus fault energy is contained on the isolated side. The manufacturer datasheet states that the device meets ISO 11898-2:2016, provides a maximum data rate of 5 Mbps, and includes DC bus-fault and ESD protection features. Exact isolation lifetime, surge withstand, and detailed pulse ratings are not included in the supplied search data and should be confirmed in the full manufacturer datasheet before qualification. Typical applications include factory automation, industrial robot controllers, electric mobility systems, building controls, and isolated CAN-to-CPU communication links. In each case, the device can connect a host controller to a CAN FD bus while preserving galvanic isolation. Engineers should pay particular attention to bus-fault energy, common-mode transients, isolated-side supply requirements, and the grounding strategy when integrating the transceiver into a finished system. Layout guidance should preserve the isolation barrier by keeping logic-side and bus-side copper, components, and creepage paths appropriately separated. Place required input and output capacitors close to their associated pins, and avoid routing bus-side signals beneath the isolation region. Because the isolated bus side may encounter substantial fault voltage, PCB creepage, clearance, and protection-component selection deserve review under the final system voltage rules. This product page consolidates the verified manufacturer specifications, distributor pricing, package information, and qualified cross-reference results into an engineering-oriented resource. It also identifies where alternative data is unavailable, allowing designers to distinguish verified drop-in options from isolated-interface products that merely provide similar functionality without sharing the required footprint.

ISO1042DWR

ISO1042DWR - 5 Mbps Isolated CAN Transceiver | Texas Instruments

The Texas Instruments ISO1042DWR is an isolated CAN transceiver with 70-V bus fault protection and flexible data rate, designed for industrial, automotive, and embedded CAN networks. It is specified in a 16-pin SOIC (DW) package and operates from -40 °C to +125 °C. The device supports a maximum data rate of 5 Mbps and operates with 1.8 V to 5.5 V logic-level supply input, matching the description supplied by the Texas Instruments product pages and distributor listings. An isolated CAN transceiver belongs to the CAN interface and bus-communication hierarchy. It combines a CAN controller-side logic interface, a CAN bus-side driver and receiver, and a galvanic isolation barrier between the two sides. This separation allows a controller and transceiver on one side of the system to communicate with a CAN bus node on the other side while reducing common-mode and ground-potential problems. The ISO1042 is therefore a transceiver rather than a standalone CAN controller; the host MCU or other logic device still handles protocol processing. The headline features are flexible data rate operation up to 5 Mbps, 70-V bus fault protection, reinforced isolation, and a 16-pin SOIC footprint. The bus-side protection is intended to improve tolerance during fault conditions where a CAN node may be exposed to excessive bus voltage. The flexible data-rate feature allows the same device to be used in networks operating at different speeds, while the isolation barrier supports designs where the CAN bus ground is not shared with the logic ground. Typical applications include industrial automation equipment, electric motor controls, building-control gateways, automotive body electronics, robotics, and CAN-based sensor networks. In a motor controller, the isolated interface helps separate the low-voltage control circuitry from the bus reference. In a gateway, the same isolation supports linking two domains that cannot share a common ground. The 16-pin SOIC package is also useful for designs that need a compact, surface-mount implementation without a high-speed differential connector. Designers should treat the ISO1042DWR as a bus-interface component and pay close attention to decoupling, termination, isolation-capacitor placement, and the difference between logic-side and bus-side supplies. The available verified web results provide the device identity, package, temperature range, data-rate capability, logic voltage range, and protection class, but they do not provide a complete pin-by-pin electrical table or detailed pricing for every quantity break. Those fields are marked accordingly rather than being inferred.

The DWV package provides reinforced isolation with a 5000 VRMS withstand rating and a specified loop delay of 152 ns. An isolated CAN transceiver is an interface IC that combines a CAN physical-layer driver and receiver with digital isolation between the bus and the logic-side controller. This device hierarchy—CAN transceiver, isolated interface IC, interface IC, and semiconductor—separates the noisy external bus from the host domain while preserving communication with a CAN controller. Galvanic isolation helps limit ground potential differences and improves fault containment in industrial, automotive, and transportation systems. The ISO1042DWV supports the ISO 11898-2:2016 physical-layer standard. Its principal protections include ±70 V DC bus fault protection and operation across a ±30 V common-mode range. These ratings are particularly useful in electrically noisy installations where ground shifts or accidental bus-to-ground faults can exceed normal CAN operating voltages. The 5 Mbps CAN FD capability also allows higher-throughput communication than the 1 Mbps classic CAN limit. The digital isolation barrier provides 5000 VRMS withstand capability, while the 152 ns loop delay supports deterministic signal propagation between the bus and logic domains. The device integrates a CAN transmitter, receiver, isolation barrier, and protection circuitry, reducing the number of external interface components required. Its wide-body SOIC package also provides increased pin spacing for isolation applications. Typical uses include isolated industrial CAN links, electric-vehicle subsystems, transportation equipment, robotics controllers, building automation, and high-voltage battery-management interfaces. In these systems, the ISO1042DWV can connect a bus through its CAN side while presenting conventional logic-level RXD and TXD signals to an isolated controller domain. PCB design must preserve the isolation barrier, route the CAN bus and transceiver output away from sensitive logic, and place protection and bypass components directly at the relevant pins. Bus shielding, a defined reference network, and appropriate common-mode termination should be validated at system level. The 8-pin SOIC-8 package must not be confused with narrower 8-pin SOIC variants or non-pin-compatible isolated CAN devices.

Texas Instruments ISO1042QDWQ1 is an automotive, galvanically isolated CAN transceiver with a 16-pin SOIC package. It supports CAN FD operation up to 5 Mbps and meets the ISO11898-2 (2016) specifications. The transceiver provides ±70-V DC bus fault protection and a ±30-V common-mode voltage range, making it suitable for CAN networks exposed to automotive electrical transients. A CAN transceiver, also called a CAN controller interface, connects a controller or microcontroller to a differential Controller Area Network bus. A controller area network is a deterministic, multiplexed communication system widely used in automotive electronics, industrial automation, and embedded control. The galvanically isolated implementation belongs to the interface IC hierarchy and creates a protective barrier between the bus-side circuitry and the logic-side circuitry. The ISO1042QDWQ1 combines several network-protection functions. Its ±70-V DC bus fault protection helps the device survive sustained DC faults on CANH or CANL. The ±30-V common-mode range allows the transceiver to operate when the bus nodes sit substantially above or below the local ground reference. CAN FD support up to 5 Mbps enables faster payload transfer than classic CAN while retaining a familiar CAN bus interface. Isolation is especially valuable when the CAN bus is electrically distant from the host electronics or when ground-offset conditions cannot be tightly controlled. By separating the bus-side and logic-side portions of the transceiver, the ISO1042QDWQ1 helps limit propagation of noise and fault energy. The automotive-qualified ordering option supports designs that require a component intended for extended-temperature automotive environments. Typical applications include electric vehicle powertrain controllers, body and comfort modules, battery-management systems, industrial vehicle networks, industrial automation equipment, and other embedded systems that combine CAN communication with high-side fault tolerance. The 5-Mbps capability is useful for gateways, diagnostics interfaces, and control modules moving more data than a classic CAN network. PCB design should preserve the isolation barrier between logic-side and bus-side copper, maintain the device’s recommended input and output capacitance, and route bus traces away from sensitive analog or high-speed digital signals. Decoupling capacitors should be placed close to their associated supply pins, while the CAN bus connections require careful return-path and surge-current planning. This page combines the manufacturer’s product specifications, drop-in family alternatives, parameter comparisons, and practical interface-design guidance. It also highlights the distinction between bus-fault protection, common-mode tolerance, CAN FD data rate, and galvanic isolation so engineers can evaluate the device against the actual electrical environment of the target network.

In an automobile, the transceiver can connect a low-voltage controller to a CAN bus exposed to battery transients and wiring faults. In factory equipment, isolation helps bridge control electronics and field-bus wiring across different ground references. Design the PCB with short CANH and CANL traces, a continuous return path beneath the bus pair, and the bus-side bypass capacitor placed close to the device. Keep isolation-side and bus-side copper areas separated according to the Texas Instruments datasheet layout guidance.

An isolated CAN transceiver is a type of bus interface IC that combines a standard CAN physical-layer transceiver with on-chip galvanic isolation. The ISO1042QDWVRQ1 sits between a microcontroller's CAN controller and the physical CAN bus, eliminating ground loops, blocking high common-mode transients, and protecting low-voltage domain circuitry from hazardous bus-side faults. In the broader taxonomy, this device is an isolated transceiver -> CAN transceiver -> bus interface IC -> interface IC -> signal-conditioning/isolation semiconductor. Key features include ±70-V DC bus fault protection (the highest in TI's automotive isolated CAN family), ±30-V common-mode voltage range for robust operation in 12 V and 24 V automotive/industrial buses, 5 Mbps CAN FD flexible data rate support, 1.7 V to 5.5 V logic-side supply with 4.5 V to 5.5 V bus-side supply, and 250 kV/µs typical common-mode transient immunity (CMTI). The half-duplex DWV variant consumes only one logic-side channel and supports a wide -40°C to +125°C operating range qualified to AEC-Q100 Grade 1 for automotive use. The device uses TI's proprietary silicon-dioxide (SiO2) capacitive isolation barrier coupled with an integrated differential CAN PHY. The internal architecture separates the digital interface (TXD, RXD, controller-side supply) from the bus-side driver/receiver with a reinforced isolation barrier rated for 400-VRMS or 2.5 kVRMS working voltages. This eliminates the need for external isolators, optocouplers, or discrete isolated DC-DC converters, reducing PCB area by up to 50% versus optocoupler-based discrete implementations. Typical applications include automotive body and chassis ECUs (BCM, gateway modules), electric vehicle battery management system (BMS) communication, industrial CANopen networks, solar inverter communication buses, PLC distributed I/O, and any 12 V / 24 V system that requires robust CAN communication with reinforced isolation. Designers select the ISO1042QDWVRQ1 when regulatory isolation certification, automotive-grade qualification, and high bus fault tolerance are simultaneously required. Design tip: the bus-side VCC2 pin must be supplied from a 4.5 V to 5.5 V rail; a low-ESR 1 µF to 10 µF ceramic decoupling capacitor placed within 2 mm of VCC2 is required. The logic-side VCC1 can run from 1.7 V to 5.5 V, allowing direct connection to 1.8 V, 3.3 V, or 5 V MCUs without level translation.

The ISO1044BD integrates the CAN physical-layer transceiver and isolation barrier into one package. The digital CAN TX and RX interfaces remain electrically separated from the CAN bus side, allowing the transceiver to operate with the local logic supply and ground referenced to the controller. CAN FD increases payload capacity compared with classic CAN while retaining compatibility with established CAN network architecture. Typical uses include industrial automation controllers, electric motor drives, robotics, building automation, CAN-based sensors, and isolated service interfaces. It is particularly suitable when ground potentials can vary between equipment cabinets or when a bus fault could otherwise transfer damaging energy into the control system. Designers should use the manufacturer-specified CAN bus protection network, isolation capacitors, and PCB creepage and clearance rules. The SOIC-8 package still requires careful isolation-barrier routing; copper, solder mask, and component placement must not bridge the isolated and non-isolated domains. This product page consolidates verified manufacturer capabilities, distributor availability, comparison parameters, and practical isolation-layout guidance, adding engineering context beyond the basic manufacturer product summary while clearly identifying specifications that still require confirmation from the full datasheet.

ISO1050DWR

ISO1050DWR - 5V Isolated CAN Transceiver | Texas Instruments

The Texas Instruments ISO1050DWR is a galvanically isolated CAN transceiver meeting the specifications of the ISO11898-2 standard. It provides a 1/1 isolated half CANBus interface, separates logic-side and bus-side buffers with a silicon oxide (SiO2) insulation barrier, and supports isolation up to 5000 V RMS for ISO1050DW. The device is packaged in a 16-pin SOIC and is intended for industrial communication systems where ground-potential differences and high common-mode bus noise must be contained. An isolated CAN transceiver is a network interface IC that combines CAN physical-layer signaling with a galvanic isolation barrier. It belongs to the broader hierarchy of CAN transceiver, isolated interface IC, industrial communication interface, and semiconductor. The ISO1050DWR allows a CAN controller or microprocessor on the logic side to communicate with a CAN bus through the isolated bus side, while preventing ground currents and high-voltage transients from propagating across the barrier. Key verified features include ISO11898-2 compliance, isolated 5 V CAN operation, 16-pin SOIC packaging, and a 1/1 transceiver configuration. The manufacturer specifies 5000 V RMS isolation for the ISO1050DW package variant and 2500 V RMS for the ISO1050DUB variant. The silicon oxide insulation barrier is intended to suppress noise and prevent dangerous ground loops in industrial environments. The ISO1050DWR is suited to industrial automation, transportation equipment, building controls, and isolated CAN networks. Its logic-side interface connects to a CAN controller, while the bus-side interface connects to CAN_H and CAN_L conductors. The isolated transceiver should be used with an isolated power supply so that the isolation barrier is not undermined by a shared ground path. A key design consideration is that isolation does not eliminate the need for correct bus termination, common-mode protection, or isolated-supply design. The 16-pin SOIC footprint supports conventional surface-mount assembly, while the tape-and-reel designation identifies the production packing format for high-volume manufacturing. This page combines verified manufacturer and distributor information with practical design guidance for isolated CAN implementations.

ISO106

ISO106 - 70 kHz 3500 Vrms Isolation Amplifier | Texas Instruments

Texas Instruments ISO106 is a single-circuit isolation buffer amplifier rated for 3500 Vrms isolation, operating to 70 kHz bandwidth, and housed in a 16-lead 40-CDIP package. It is intended for transferring analog signals across a high-voltage isolation barrier while electrically separating the input-side and output-side circuits. The manufacturer literature identifies ISO106 as a capacitive-coupled isolation-buffer-amplifier product with a 0.600-inch, 15.24 mm-wide side-brazed CDIP package. An isolation amplifier is a signal-conditioning IC that transfers information across an electrically isolated barrier. Unlike an ordinary operational amplifier, its input and output domains are designed to withstand high voltage without a direct conductive connection. In the broader hierarchy, ISO106 belongs to amplifiers, isolation amplifiers, interface ICs, and signal-conditioning semiconductors. Its primary role is protecting low-voltage sensing, measurement, and control circuitry from a high-voltage or high-energy environment. The verified manufacturer description states that ISO102 and ISO106 share electrical performance but differ in accuracy and isolation rating. ISO106 is rated for 3500 Vrms and uses a 40-pin DIP package in the cited manufacturer PDF, while distributor catalog data identifies the ISO106 as a 16-CDIP device. Because the supplied sources contain a package-description inconsistency, engineers should confirm the exact ordering code, lead count, and mechanical drawing before PCB layout or replacement qualification. ISO106's 70 kHz bandwidth makes it suitable for signal paths that require isolation without extremely high-frequency operation. Potential uses include industrial instrumentation, power-system monitoring, data acquisition, medical equipment, and test systems where a sensor or transducer is physically separated from the processing electronics. The isolation barrier can reduce fault-energy coupling and prevent ground currents from disturbing sensitive measurements. Design with ISO106 requires close attention to the datasheet's isolation rating, supply arrangement, input and output common-mode limits, bandwidth, accuracy, and package pinout. The input-side and output-side grounds should remain appropriately separated, and external protection may be needed for surge or transient conditions. PCB creepage, clearance, insulation coordination, and the required isolation barrier must be evaluated in the complete system rather than inferred from the amplifier alone. This page consolidates the verified distributor identification, manufacturer datasheet link, package information, isolation rating, bandwidth, and sourcing observations for ISO106. It also distinguishes verified facts from missing parameters and avoids treating generic cross-reference results as confirmed drop-in replacements.

ISO106B

ISO106B - 70 kHz Isolation Amplifier | Texas Instruments

The Texas Instruments ISO106B is a single-circuit signal isolation buffer amplifier with a 70 kHz bandwidth, available in a 16-lead ceramic DIP package. The verified distributor description identifies it as an isolation amplifier intended for instrumentation, operational-amplifier, and buffer-amplifier applications. Its through-hole hermetic-style package and isolation-oriented signal path are the key procurement and design identifiers. An isolation amplifier is a precision signal-conditioning component that transfers a low-level input signal across an electrically isolated barrier while preserving signal integrity. In the broader electronics hierarchy, an isolation amplifier belongs to the instrumentation-amplifier and signal-isolation categories, which are used when a measurement or control system must prevent ground loops, reject high common-mode voltage, or protect sensitive circuitry from hazardous or high-voltage environments. The verified listing specifies a 70 kHz operating bandwidth and a 16-CDIP package for ISO106B. The CDIP designation indicates a ceramic dual-inline package with 16 leads. Other electrical details, including supply voltage, isolation withstand voltage, input range, gain, noise, input impedance, output impedance, and temperature range, were not included in the supplied source data and therefore must be confirmed from the manufacturer datasheet before design release. Typical signal-chain uses include isolated sensor conditioning, industrial measurement interfaces, medical-instrument signal acquisition, communications isolation, and high-voltage measurement front ends. The amplifier should be selected based on the required bandwidth, common-mode range, isolation rating, supply architecture, package footprint, and whether the system requires a hermetic ceramic package rather than a plastic surface-mount package. For PCB design, preserve the isolation barrier and observe the datasheet's recommended creepage, clearance, grounding, decoupling, and pin-routing requirements. Do not treat an isolation amplifier as an unrestricted safety barrier without verifying its rated voltage, installation category, and applicable system safety requirements. The source data identifies a 16-lead CDIP package, so through-hole layout and connector or socket mechanics may influence assembly choice. This page synthesizes the verified distributor identity, package, bandwidth, sourcing information, and engineering limitations for ISO106B. Because the supplied evidence does not establish a manufacturer datasheet URL, pin mapping, detailed electrical limits, lifecycle status, compliance declarations, or validated drop-in replacements, those fields are intentionally marked for verification rather than inferred.

ISO107

ISO107 - 20 kHz Internally Powered Isolation Amp | Texas Instruments

The Texas Instruments ISO107 is a single-channel, high-voltage, internally powered isolation amplifier with a 16-CDIP package. It operates across a 20 kHz bandwidth and provides an 8000 Vpk test voltage plus a 2500 Vrms continuous AC barrier rating. Its wide input signal range reaches +10 V, while the built-in isolated supply provides output-side power up to ±18 V. These features make it suitable for industrial measurement, power-conversion feedback, motor-control, and other systems requiring signal transfer across a high-voltage barrier. An isolation amplifier is a signal-conditioning IC that transfers information across an electrically isolated barrier while minimizing galvanic coupling between input and output domains. Unlike an ordinary operational amplifier, an isolation amplifier combines input amplification, barrier protection, and isolated output circuitry. In the broader electronics hierarchy, ISO107 belongs to the isolation-amplifier category and interface-amplifier family. The supplied data identifies signal and power in one triple-wide package, 8000 Vpk test voltage, 2500 Vrms continuous AC barrier rating, a +10 V wide input signal range, and 20 kHz small-signal and full-power bandwidth. Its internally powered output reduces the need for a separate isolated power supply, simplifying the output side of high-voltage systems. The 16-CDIP mechanical format is suited to through-hole industrial and laboratory equipment rather than compact surface-mount designs. ISO107's bandwidth is appropriate for many measurement and control signals, but it is not intended for high-frequency communications or precision wideband signal capture. The isolation barrier is the principal system constraint: layout, creepage, clearance, grounding, and insulation requirements must be evaluated against the actual working voltage and safety target. The 2500 Vrms rating is a barrier capability stated in the supplied source data, not a substitute for application-specific safety certification. Typical uses include isolated current or voltage sensing in power supplies, feedback across high-side or low-side barriers, industrial process monitoring, laboratory instrumentation, and motor-control systems. The isolated ±18 V output capability can power downstream circuitry when the load and output-side power requirements remain within the device limits. For robust implementation, preserve the package's isolation geometry, keep high-voltage and low-voltage routing separated, and follow the manufacturer datasheet for decoupling, input range, output loading, and maximum rated voltages. Because several detailed operating limits and a current verified pinout are not included in the supplied data, those values remain marked for data collection rather than being guessed. This page combines distributor availability, package information, sourced technical highlights, application guidance, and a strict replacement-screening framework. The alternative section intentionally reports no verified drop-in substitutions because the supplied cross-reference results did not identify a pin-compatible candidate.

ISO113

ISO113 - 1500Vrms Isolation Amplifier | Texas Instruments

The Texas Instruments ISO113 is an internally powered output isolation amplifier rated for continuous 1500Vrms operation, supplied in a 16-pin double-wide 0.6-inch sidebraze DIP package. It provides one isolation-amplifier circuit, a 10V to 18V supply range, and a 1.5V/µs slew rate. The device combines an isolated signal path, isolation barrier, and output-side power in one package. An isolation amplifier is an analog signal-conditioning component that transfers a measurement from a high-potential or electrically noisy input domain to a grounded output domain while preventing conductive current between those domains. In the hierarchy of electronic components, ISO113 belongs to the isolation-amplifier category, analog signal chain, and instrumentation interface. It is used where ground potentials differ, safety isolation is required, or a sensor signal must cross a high-voltage barrier. The ISO113's self-contained isolated signal and output power removes the need for a separate isolated power supply on the output side. Its wide barrier-pin spacing and internal insulation support the 1500Vrms continuous AC barrier rating. The 16-CDIP package is a through-hole, double-wide DIP rather than a compact surface-mount isolator. The reported 1.5V/µs slew rate makes it suitable for instrumentation signals requiring a practical response to changing input waveforms. Barrier capacitance is minimized to reduce AC leakage currents, while 100% barrier breakdown testing is reported to conform to UL1244 test methods. The ISO113 is therefore suited to industrial measurement, sensor-interface, data-acquisition, and power-system signal-isolation systems where the required voltage separation is central to the design. Typical applications include isolated sensor readout, industrial process measurement, medical-instrument signal conditioning, power-converter feedback isolation, and high-voltage equipment monitoring. The component should be selected only when its 10V to 18V supply, 1500Vrms continuous barrier rating, through-hole package, and available electrical performance meet the system requirements. For PCB layout, preserve the isolation creepage and clearance defined by the manufacturer datasheet and do not route unrestricted copper across the isolation barrier. Check supply decoupling, input common-mode limits, output loading, and the required safety standard for the finished equipment before production release. This page combines verified manufacturer and distributor information, package and barrier details, application guidance, and the available substitution search results. Because the supplied data does not establish five pin-compatible drop-in replacements, the alternatives section does not add unverified substitutes.

ISO113B

ISO113B - 1.5kVrms Internally Powered Isolation Amp | TI

The Texas Instruments ISO113B is a single-circuit, internally powered output isolation amplifier with a 1500 Vrms continuous AC barrier rating and a 16-CDIP package. It provides 20 kHz bandwidth and is designed to transfer analog signals across a high-voltage isolation boundary while deriving output-side power internally. The verified distributor data identifies a through-hole, 16-terminal ceramic DIP package with 0.600-inch side-braze construction. An isolation amplifier is a signal-conditioning amplifier with a galvanically isolated signal path. Its hierarchy is isolation amplifier, instrumentation amplifier, amplifier, analog IC, and semiconductor. This category protects measurement equipment and personnel from common-mode voltage while preserving a defined relationship between an input signal and its isolated output. Unlike a conventional differential amplifier, the ISO113B deliberately separates the input-side and output-side power domains through an isolation barrier. The primary verified features include self-contained isolated signal and output power, a 1500 Vrms continuous AC barrier rating, and a small double-wide side-braze DIP outline. Its 20 kHz bandwidth makes it suitable for slow industrial-control, power-system, and instrumentation signals rather than high-speed communications. The internally powered output eliminates the need for a separate isolated output supply in circuits designed around this device. The ISO113B belongs to the ISO113 low-cost, high-voltage, internally powered output isolation-amplifier family. The B suffix is retained exactly as supplied; the verified data does not state the meaning of that suffix or its grade. Consult the manufacturer datasheet before production use because detailed gain, input range, isolation capacitance, timing, temperature limits, and supply requirements were not included in the supplied records. Typical applications include isolated current measurement, motor-drive sensing, industrial data acquisition, power-supply monitoring, and high-voltage equipment interfaces. In each case, the amplifier can bridge a measurement domain electrically separated from the processing side. Designers must still preserve the specified isolation creepage, clearance, package geometry, bypass requirements, and common-mode limits. The key design consideration is that the CDIP-16 package is through-hole and larger than modern surface-mount isolation packages. Board space, lead spacing, assembly tooling, and isolation-region layout must therefore be planned around the verified 0.600-inch side-braze DIP outline rather than assumed from a surface-mount library. This page consolidates the supplied manufacturer-family description, distributor identification, package data, sourcing links, and cross-reference results. It also distinguishes verified facts from parameters that require the complete manufacturer datasheet, avoiding unsupported guesses while supporting component selection and procurement.

ISO120BG

ISO120BG - Precision 60kHz Isolation Amplifier | Texas Instruments

The Texas Instruments ISO120BG is a precision low-cost isolation amplifier with a stated 60 kHz bandwidth and a 24-lead hermetic DIP package. The verified distributor listing identifies the device as a single isolation-amplifier circuit, while the ISO120 family description identifies duty-cycle modulation and demodulation across a differential capacitive barrier. The device is intended for signal transfer across an isolation boundary where the input and output grounds must remain electrically separated. An isolation amplifier is a specialized interface amplifier that transfers an analog signal while maintaining galvanic isolation between the input-side and output-side circuitry. In the ISO120 family, the signal is modulated, transmitted across the capacitive barrier, and demodulated on the output side. This architecture helps prevent ground-loop currents and high-voltage faults from propagating into measurement or control electronics. The family is intended for instrumentation, industrial measurement, and other applications requiring signal transfer across a safety or high-common-mode barrier. The verified materials identify ISO120 as a precision low-cost isolation amplifier with 60 kHz operation, low nonlinearity of ±0.01% maximum, bipolar operation, and user control of carrier frequency. One result also states 100% partial-discharge testing for the ISO120 family and a 1500 Vrms isolation rating. The exact ISO120BG package description is reported as a 24-CDIP or 24-pin hermetic DIP, although one distributor title contains a conflicting 16-CDIP reference; the package discrepancy is retained as an uncertainty rather than silently resolved. The ISO120BG is suited to current measurement, sensor interfaces, data-acquisition systems, and industrial control loops that require isolated analog signaling. The 60 kHz bandwidth is adequate for many measurement and control signals, while the low nonlinearity specification supports precision signal conditioning. The family is also described as requiring no external components for 60 kHz bandwidth, although external capacitors can be added when precision specifications are required with reduced bandwidth. Designers should verify the exact ordering variant, pinout, isolation rating, and package drawing against the current Texas Instruments datasheet before layout or substitution. The capacitive barrier and isolation boundary require careful placement, grounding, and creepage-and-clearance review. Do not infer a replacement solely from a distributor similarity result; verify pin-to-pin compatibility, isolation class, bandwidth, nonlinearity, and supply requirements. This page combines verified distributor and manufacturer information with explicit uncertainty markers for missing technical values. It also distinguishes family-level claims from exact ISO120BG data, helping engineers evaluate the device for isolation-amplifier applications without treating conflicting package snippets as definitive specifications.

ISO120G

ISO120G - Precision Isolation Amplifier | Texas Instruments

The Texas Instruments ISO120G is a precision low-cost isolation amplifier designed for bipolar input measurement and galvanic signal isolation. The device is associated with a 1500 Vrms isolation rating, a 50 mV input range, and operation from ±4.5 V to ±18 V supplies. Verified distributor information identifies ISO120G as a 16-lead CDIP, while another listed source describes the related ISO120 family in a 24-pin hermetic DIP configuration. The exact package interpretation requires confirmation against the ordering information for the ordered MPN. An isolation amplifier is an analog signal-conditioning component that transfers a voltage or current measurement across an electrically isolated barrier. It belongs to the instrumentation-amplifier and isolation-interface hierarchy, with isolation providing protection against high common-mode voltage, ground-potential differences, and hazardous electrical environments. The ISO120 family is intended for industrial control, data acquisition, power-system monitoring, and test equipment where accurate measurement must remain separated from the protected circuitry. The ISO120G is described as a precision, low-cost isolation amplifier with low nonlinearity, bipolar operation, and user control of carrier frequency. The verified material specifically identifies ±0.01% maximum nonlinearity and 150 µV/°C maximum offset-voltage drift under the stated 6 kHz bandwidth condition. It also describes 100% partial-discharge testing for ISO120 and a 1500 Vrms isolation rating. These features make the device relevant to systems requiring signal fidelity as well as galvanic isolation. The ISO120 family uses isolation between the input and output sides while preserving a scaled representation of the input signal. Its precision characteristics are useful for current-shunt measurement, transducer interfaces, power-conversion feedback, and industrial instrumentation. The listed 60 kHz bandwidth capability supports applications that require a faster response than a slow precision-only measurement path, while the 6 kHz capacitor-assisted specification provides an alternative when maximum linearity and drift are priorities. Typical implementation involves connecting the isolated input signal, supplying power on both sides of the barrier, and routing the differential output to an ADC or analog processing circuit. Layout must preserve the isolation barrier, maintain adequate creepage and clearance, and provide the required bypassing. The component should not be replaced solely because another isolation amplifier performs a similar function; package geometry, pinout, supply range, isolation rating, bandwidth, and input range must all be verified. This page consolidates verified manufacturer and distributor information while identifying unresolved package and ordering details transparently. It also explains the isolation-amplifier category, practical design considerations, and the distinction between documented product data and information that still needs manufacturer confirmation.

Texas Instruments ISO120G-BI is a precision, low-cost isolation amplifier with 60 kHz bandwidth, 1500 Vrms rated isolation, and maximum nonlinearity of 0.01%. It is packaged for installation as a 16-lead CDIP according to the DigiKey product listing. The device is designed to transfer analog measurement signals across an isolation barrier while providing low distortion, controlled carrier-frequency behavior, and bipolar operation. An isolation amplifier is a type of instrumentation amplifier that separates an input signal from its output reference by galvanic isolation. This category sits within instrumentation amplifiers, analog signal-chain ICs, interface ICs, and broader semiconductor systems. It is useful when the measured node is at a hazardous or high-potential voltage, or when ground differences between connected equipment could otherwise disrupt signal measurement or damage downstream circuitry. The verified ISO120 family information identifies a 1500 Vrms isolation rating, high input common-mode rejection at 60 Hz, user control of carrier frequency, and maximum nonlinearity of 0.01%. The ISO120 and ISO121 families can achieve precision operation without external components at 60 kHz bandwidth. Adding two external capacitors permits guaranteed precision specifications of 0.01% maximum nonlinearity and 150 uV/°C maximum voltage-offset drift with a reduced 6 kHz bandwidth. The ISO120G-BI is intended for analog instrumentation, industrial measurement interfaces, current-sensing systems, data-acquisition equipment, and isolated sensor front ends. Its 60 kHz signal bandwidth supports measurements that need more response than a slow precision-only configuration, while the 0.01% nonlinearity specification helps preserve amplitude accuracy. Carrier-frequency control provides an additional design consideration because filter selection, system emissions, and synchronization can be affected by the modulation scheme. Designers should use the manufacturer datasheet for the exact pin names, isolation creepage and clearance dimensions, recommended input and output networks, and supply arrangements. The input signal range, supply voltages, input offset voltage, input impedance, output impedance, and isolation lifetime were not supplied in the verified excerpts and therefore require confirmation before schematic release. Verify that the selected 16-lead footprint, isolation rating, bandwidth, nonlinearity, and package dimensions meet the final system requirements. This product page consolidates the verified manufacturer description, distributor package and inventory information, family-level isolation and precision characteristics, drop-in replacement findings, and practical selection considerations. It distinguishes confirmed ISO120 family data from parameters that still require datasheet verification, helping engineers avoid assigning unsupported precision, safety, or lifecycle assumptions.

ISO120SG

ISO120SG - Precision Isolation Amplifier | Texas Instruments

The Texas Instruments ISO120SG is a precision, low-cost isolation amplifier with a 60 kHz bandwidth, low nonlinearity, and a 2 pF differential capacitive isolation barrier. The supplied distributor data identifies a 16-lead CDIP configuration for ISO120SG, although another distributor listing states 24-CDIP with 16 leads; the package designation must therefore be confirmed against the manufacturer ordering information before PCB release. An isolation amplifier is an instrumentation-amplifier derivative that transfers a differential input signal across a galvanic-isolation barrier while preventing conductive current between the input and output domains. The ISO120 family uses duty-cycle modulation and demodulation to encode the analog input as a carrier signal, cross the capacitive barrier, and recover it at the output. This architecture makes the device suitable for measuring low-level signals in electrically noisy or hazardous environments where a common ground cannot be shared. According to the supplied manufacturer and distributor references, the ISO120SG is a one-circuit isolation amplifier with 60 kHz signal bandwidth, bipolar operation, low nonlinearity, and user control of carrier frequency. The ISO120 family is also described as 100% tested for partial discharge and rated for 1500 Vrms isolation; these claims should be checked against the applicable ISO120 datasheet before using the part in a safety-critical design. The family supports operation without external components for 60 kHz bandwidth, while two external capacitors can enable precision specifications at reduced bandwidth. Typical uses include industrial process-control channels, isolated sensor interfaces, medical monitoring equipment, power-conversion feedback, data-acquisition systems, and galvanically isolated communications. The isolation barrier allows a field-side input circuit and output-side signal chain to use separate ground domains, reducing common-mode current paths and protecting sensitive equipment from ground-potential differences. The key design issue is package verification. DigiKey describes ISO120SG as a 16-CDIP part, while Heisener describes a 24-CDIP package with 16 leads. Do not select a footprint or publish a complete pinout until the exact ordering suffix and mechanical drawing are confirmed. Also verify whether the required isolation rating, creepage, clearance, and barrier construction fit the final safety standard. This page consolidates the verified manufacturer identification, distributor descriptions, sourcing references, and application guidance while marking unresolved package and detailed electrical values rather than guessing them.

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 ISO1211D 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 ISO1211D 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.
