ISO100BP 概述
An isolation amplifier is a precision analog signal-conditioning device used when a measurement originates on an electrically hazardous, high-impedance, or ground-referenced circuit. It combines input-stage gain, electrical isolation, and output amplification so that a low-level sensor signal can be transferred to a measurement system while minimizing ground-loop errors and common-mode hazards. The ISO100BP’s optically coupled architecture supports industrial instrumentation, process control, medical monitoring, and other applications requiring reinforced signal separation.
Verified product information identifies one isolation-amplifier circuit, an 18-CDIP package, through-hole mounting, 18 terminals, 8 mA supply current, a 60 kHz operating description, and 18-pin construction. The datasheet search result also states that the device is 100% tested for 750 V continuous isolation, has maximum ultra-low leakage of 0.3 µA at 240 V and 60 Hz, and accepts current or voltage input configurations. Exact gain, supply-voltage, accuracy, and temperature limits were not supplied in the verified data and therefore require confirmation from the manufacturer datasheet before design release.
The device is intended for analog front ends where preserving signal integrity across an isolation barrier is more important than minimizing package size. Its through-hole CDIP construction can simplify prototyping and repair, while the isolation barrier allows a field-side input circuit and a grounded output interface to remain electrically separate. Input and output grounding, supply bypassing, component tolerances, and barrier creepage must be evaluated as a complete isolation system rather than inferred from the amplifier alone.
Typical uses include isolated current measurement, industrial process sensors, laboratory instrumentation, and medical or diagnostic signal acquisition. In each case, the sensing front end can operate near a high-voltage node while the output is referenced to a lower-voltage system. The design must still account for input common-mode range, isolation capacitance, leakage, bandwidth, gain configuration, supply sequencing, and applicable safety requirements.
For a new design, use the ISO100BP when its verified 18-CDIP footprint, current-or-voltage input flexibility, 60 kHz bandwidth description, and 750 V continuous isolation rating fit the mechanical and safety requirements. Do not substitute an unspecified amplifier solely by function; verify every pin, parameter, creepage dimension, and isolation requirement against the official datasheet.

典型应用
ISO100BP 适用于 6 应用s: Industrial Process Current Measurement, High-Voltage Sensor Interface, Laboratory Instrumentation, Medical Signal Acquisition, Data Acquisition and Test Systems, Power Electronics Feedback Monitoring.
Industrial Process Current Measurement
The ISO100BP fits isolated current-measurement front ends where a field sensor produces a current signal at a potentially noisy or high-potential node. Its current-input relationship is listed as VOUT/IIN = RF, allowing the signal conversion to be established with an external feedback resistor, while the listed 750 V continuous isolation separates the sensing side from the control electronics. The 60 kHz bandwidth description is useful for many industrial process signals, but engineers must confirm the exact gain, accuracy, common-mode limits, and frequency-response details in the full datasheet. Layout should also preserve the required isolation creepage and clearance rather than routing high-voltage and low-voltage conductors beneath or between the same package terminals without planning.
推荐
High-Voltage Sensor Interface
The ISO100BP is suited to sensor interfaces that must measure a signal referenced to a hazardous or substantially different ground potential. Its optically isolated instrumentation-amplifier architecture provides a defined separation between input and output domains, while the listed 0.3 µA maximum leakage at 240 V and 60 Hz helps constrain unwanted current through the barrier. The device can accept either current or voltage input, making it relevant to pressure, temperature, and current transducers whose output format varies. Because the verified information does not provide exact common-mode voltage, supply range, or safety-certification details, the application must be validated against the complete manufacturer documentation and the applicable insulation standard.
推荐
Laboratory Instrumentation
The ISO100BP can be used in laboratory measurement systems where a DUT or sensor operates at a floating potential and the data-acquisition electronics require a protected reference. The single-channel 18-CDIP package is practical for a through-hole prototype or a dedicated instrument front end, and the listed 60 kHz bandwidth provides a defined starting point for signal-chain selection. For laboratory use, calibrate the complete channel rather than relying only on nominal gain, and account for leakage, isolation capacitance, source impedance, and input filtering. The manufacturer datasheet should define the required resistor network, bypass capacitors, startup behavior, and output drive before final analog-layout release.
推荐
Medical Signal Acquisition
The ISO100BP may be considered for medical signal-acquisition front ends only when the complete system requirements, including patient protection, applicable medical standards, isolation limits, leakage, and fault behavior, are independently verified. Its listed 750 V continuous isolation and low-leakage architecture can help separate a sensing domain from downstream electronics, but the amplifier alone does not establish medical certification. The input signal bandwidth must fit within the listed 60 kHz description, while the external protection network, isolation barrier, creepage, clearance, and output grounding require a safety-led design review. No medical qualification is asserted by the supplied verified data.
推荐
Data Acquisition and Test Systems
The ISO100BP is appropriate for data-acquisition and test systems in which a measured node must remain electrically separate from the host instrument. The 18-CDIP through-hole package supports conventional prototyping, and the current- or voltage-input flexibility permits the same isolation architecture to serve different sensor outputs. The 60 kHz bandwidth description is suitable for a broad class of low-to-moderate-bandwidth measurements, but the engineer should verify gain accuracy and input filtering for the required sample rate. Use guarded layout, defined return paths, and manufacturer-referenced bypass arrangements to reduce leakage and capacitive coupling across the isolation boundary.
推荐
Power Electronics Feedback Monitoring
The ISO100BP can be evaluated for power-electronics feedback monitoring when a current or voltage measurement must be transferred across a high-voltage switching domain without sharing its ground reference. Its listed isolation rating and low-leakage specification make it relevant to inverter, converter, and motor-control monitoring architectures, but the device’s actual common-mode voltage and transient withstand requirements must be checked against the power stage. The 60 kHz bandwidth description is a useful starting point for control-feedback bandwidth, yet propagation delay, isolation capacitance, and component tolerances still need datasheet confirmation. Do not infer safety compliance from the isolation rating alone; verify the complete barrier and board construction.

设计说明
Treat the ISO100BP as an isolation barrier, not as an ordinary through-hole amplifier. Keep high-voltage and low-voltage copper, components, and test access physically separated according to the manufacturer’s creepage, clearance, and insulation guidance. The verified data confirms 750 V continuous isolation, but it does not provide board dimensions or working-voltage derating; those values must come from the official datasheet and the final insulation standard before layout approval.
Design the input and output supplies around the verified 8 mA ISO100BP supply-current description, while allowing for resistor networks, protection components, and downstream loading. Place required bypass capacitors close to the relevant supply and ground pins using the manufacturer’s recommended topology. Because the supplied data does not state the supply-voltage range or capacitor values, do not select those components from memory; verify them in the datasheet and account for startup and supply-sequencing requirements.
Do not interpret the 750 V isolation rating as permission to remove board-level creepage or clearance requirements. High-impedance sensor nodes can be especially sensitive to the listed maximum 0.3 µA leakage at 240 V and 60 Hz, so estimate the resulting error using the actual node impedance and confirm the full isolation specification. Also verify every pin against the official 18-CDIP pinout before substituting or redesigning the board.
Use the ISO100BP’s listed 60 kHz bandwidth as an initial signal-chain constraint and determine whether the complete front end can support the required rise time and measurement accuracy. External input filtering may reduce broadband noise but can also reduce usable bandwidth or disturb the isolation transfer function. Confirm gain accuracy, frequency-response limits, propagation delay, and isolation capacitance in the manufacturer documentation before setting the filter corner.
合规信息
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The 750 V continuous isolation value is an electrical isolation specification, not a certification claim.
