ISO107 概述
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.

典型应用
ISO107 适用于 6 应用s: Isolated Power-Supply Feedback, Industrial Process Isolation, Motor-Control Isolation, High-Voltage Sensor Interface, Laboratory Instrumentation, Isolated Data Acquisition.
Isolated Power-Supply Feedback
The Texas Instruments ISO107 is a strong fit for power-supply feedback because it combines a 20 kHz bandwidth with isolated output-side power up to ±18 V. Place the amplifier across the feedback boundary so the control side receives a signal referenced to the isolated domain without a direct ground connection. Its 8000 Vpk test voltage and 2500 Vrms continuous AC barrier rating support high-voltage design work, although actual working voltage, creepage, clearance, and leakage must still be checked. The 20 kHz limit is appropriate for many loop-control signals rather than high-frequency switching waveforms.
推荐
Industrial Process Isolation
ISO107 can transfer a process measurement across an industrial isolation barrier when the measured signal remains within the supplied +10 V input range and the required bandwidth is below 20 kHz. Its internally powered output reduces the number of separate isolated rails required on the measurement side, while the 16-CDIP package supports through-hole industrial construction. The design must preserve the intended isolation geometry and validate the barrier rating for the actual installation, including cable transients and grounding conditions.
推荐
Motor-Control Isolation
The ISO107 is applicable to motor-control systems that need to transfer a control or feedback signal across a high-voltage barrier. Its 20 kHz small-signal and full-power bandwidth is useful for slower feedback loops, diagnostic signals, and supervisory control channels, while the isolated ±18 V capability can support compatible output-side biasing. The device is not a gate driver or motor driver, so external switching and protection circuitry remains necessary. Verify input common-mode limits and output loading from the datasheet before connecting it to a power stage.
推荐
High-Voltage Sensor Interface
ISO107 is suited to sensor interfaces that require a protected measurement path across a high-voltage barrier. The supplied +10 V input signal range can accommodate appropriately scaled sensor outputs, and the 2500 Vrms continuous AC barrier rating provides a defined isolation capability for suitable systems. Because input offset, bias current, common-mode range, and linearity are not present in the verified data, a precision sensor design should obtain the complete datasheet before calculating error budgets or selecting resistor values.
推荐
Laboratory Instrumentation
The ISO107's internally powered isolation and 20 kHz bandwidth make it useful in laboratory equipment where a measurement channel must connect to a grounded instrument or where hazardous and safe domains must remain separated. Its 16-CDIP package favors prototype and legacy-style instrument construction. Designers should account for ceramic-package thermal behavior, connector creepage, and the distinction between the stated 2500 Vrms barrier rating and any required laboratory safety standard. A separate isolated low-voltage supply may still be needed for downstream circuitry beyond the stated ±18 V capability.
推荐
Isolated Data Acquisition
ISO107 can serve as the analog isolation front end in a data-acquisition system when the source bandwidth is limited to the stated 20 kHz. The isolated output-side supply capability of ±18 V can simplify biasing for compatible downstream stages, while the input signal range of +10 V provides a basis for selecting front-end attenuation. The complete channel must still meet the acquisition system's settling, sampling, common-mode, and safety requirements. Confirm the ISO107 pinout and output-load limits before laying out the 16-CDIP footprint.

关键差异点
- Combines signal conditioning and isolated power in one triple-wide package （对比 Generic discrete isolation signal chain)
- Supports a stated 2500 Vrms continuous AC barrier rating （对比 Lower-rated isolation amplifier)
- Provides 20 kHz bandwidth in both small-signal and full-power modes （对比 Narrow-band isolation amplifier)
- Offers isolated output-side power to ±18 V （对比 Isolation amplifier requiring separate isolated supply)
设计说明
Preserve the ISO107's isolation geometry with the 16-CDIP footprint rather than routing high-voltage and low-voltage copper beneath or around the barrier in a way that defeats the intended creepage and clearance. Confirm the actual package drawing, pin names, and keep-out requirements from the manufacturer datasheet before layout. The supplied data does not include a verified pinout or land pattern, so do not derive either from distributor text.
Do not treat the 2500 Vrms continuous AC barrier rating as a universal safety approval. The actual working voltage, transient environment, pollution degree, insulation material, creepage distance, clearance, and applicable safety requirements must be evaluated by the system designer. ISO107's 8000 Vpk test voltage is also a device test capability, not a blanket rating for every field installation.
The supplied ISO107 bandwidth is 20 kHz for both small-signal and full-power operation. Use that limit when defining analog and digital signal paths, and check filter corner frequencies so that loop dynamics remain stable. Because input offset, common-mode range, slew rate, and output drive are not present in the verified data, obtain those specifications before designing precision or high-loading circuits.
ISO107 includes built-in isolated power up to ±18 V, but the available output current and external-load limits are not included in the verified sources. Treat the isolated output as a regulated functional block rather than an unrestricted supply. Confirm its load current, startup behavior, decoupling requirements, and whether downstream circuits share the isolated ground before connecting any external sensor or controller.
The 16-CDIP side-brazed ceramic package is mechanically different from a standard plastic DIP and may have different thermal behavior. If the circuit dissipates meaningful power, calculate junction temperature using the manufacturer package data rather than assuming a generic DIP rating. The supplied data does not provide power dissipation, thermal resistance, or ambient-temperature limits, so those values must be obtained from the datasheet before production release.
合规信息
The supplied web results do not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. AEC-Q100 is recorded as not_applicable because no automotive qualification claim is supplied for this analog isolation amplifier.
