ISO100CP 概述
An isolation amplifier belongs to the signal-chain hierarchy of operational amplifiers and instrumentation amplifiers, but its defining function is galvanic isolation between input and output domains. This category transfers an analog measurement across a high-impedance barrier while limiting electrical current between the two sides. The ISO100CP is therefore suited to systems where a sensor or shunt is electrically connected to hazardous, high-voltage, or earth-referenced equipment that must remain separately controlled.
The part supports two transfer relationships identified in the source material: VOUT/IIN equals RF for current-input use and VOUT/VIN equals RF/RIN for voltage-input use. Its 100% tested 750 V continuous isolation capability supports robust reinforced separation where the application and system safety requirements permit. The 60 kHz bandwidth is suitable for measurement signals that need accurate transfer without operating as an ultra-low-frequency instrumentation amplifier.
Optically coupled internal construction provides the barrier function, while the external resistors establish current- or voltage-to-output scaling. Because the verified source does not publish the complete electrical tables or a complete pin map, resistor values, gain tolerance, supply limits, common-mode range, and settling performance should be taken directly from the manufacturer datasheet before design release. Verify that the complete 18-pin CDIP footprint and pin names match the target PCB.
Typical uses include isolated current measurement, power-converter control feedback, industrial sensor interfaces, instrumentation channels, and high-voltage test equipment. The key engineering consideration is that isolation rating does not replace application-specific safety design: creepage, clearance, barrier construction, insulation coordination, and enclosure requirements must be evaluated separately.
The ISO100CP combines a 60 kHz isolation-amplifier channel, 750 V continuous isolation rating, 0.3 uA maximum leakage specification, and 18-CDIP package in one through-hole device. It is appropriate when the system needs a conventional resistor-programmed isolation signal path rather than a small surface-mount digital isolator.
This page synthesizes the supplied distributor information, manufacturer-linked datasheet material, package facts, sourcing context, and design cautions. Because no verified pin-compatible substitute was returned by the cross-reference search, it does not invent a five-part replacement list or present unreferenced competitor devices as drop-in alternatives.

典型应用
ISO100CP 适用于 6 应用s: Isolated Shunt Measurement, Industrial Sensor Isolation, Power-Converter Control Feedback, High-Voltage Test and Measurement, Current-Mode Control Interfaces, Instrumentation and Data Acquisition.
Isolated Shunt Measurement
The ISO100CP fits isolated current measurement because the verified datasheet text specifies VOUT/IIN = RF for current-input operation. A shunt can be placed on the high-side or low-side according to the application circuit, while the isolation amplifier transfers the measured current to a grounded controller side. Its 60 kHz bandwidth allows the channel to handle substantially faster variation than a precision low-frequency meter, although the shunt value and amplifier input network must satisfy the manufacturer's resistor and bias requirements.
推荐
Industrial Sensor Isolation
The Texas Instruments ISO100CP is applicable when a transducer is located at a high-impedance or earth-referenced boundary and its measurement must be transferred into another electrical domain. The optically coupled isolation topology and verified 750 V continuous isolation rating help limit electrical coupling, while 60 kHz bandwidth supports faster sensor signals than a static precision amplifier. The circuit must provide separate supply arrangements as required by the datasheet and must include filtering appropriate to the sensor output.
推荐
Power-Converter Control Feedback
ISO100CP can condition a feedback-control signal when the power stage and controller require isolation. The verified 60 kHz bandwidth is relevant to converter loops that cannot tolerate a very slow isolation path, and the 0.3 uA maximum leakage specification at 240 V RMS, 60 Hz provides evidence of low barrier leakage. Loop compensation, propagation delay, gain tolerance, and stable resistor values remain to be selected from the full datasheet rather than inferred from the brief source excerpt.
推荐
High-Voltage Test and Measurement
The ISO100CP is relevant to isolated test channels because it combines a 750 V continuous isolation rating with a 60 kHz bandwidth and through-hole 18-CDIP construction. It can transfer a bounded measurement signal from a hazardous test domain into lower-energy equipment, reducing common-mode effects across the isolation boundary. Engineering must still establish working voltage, clearance, creepage, pollution degree, insulation type, fuse or resistor strategy, and enclosure compliance for the complete apparatus.
推荐
Current-Mode Control Interfaces
The ISO100CP may be used where a current command or sensed current must cross an isolation boundary in a control system. Its current-input equation, VOUT/IIN = RF, provides a direct design starting point, while 60 kHz bandwidth gives the loop designer a stated operating band. The verified excerpt does not include input impedance, permitted common-mode voltage, or supply requirements; these values must be confirmed before selecting external current sources or protection components.
推荐
Instrumentation and Data Acquisition
The ISO100CP supports an isolated instrumentation channel when a sensor output must be acquired without sharing a ground reference with the host system. Voltage-input and current-input configurations allow reuse across different transducers, while the 60 kHz bandwidth is useful for dynamic measurements. For multi-channel acquisition, evaluate channel-to-channel isolation, source impedance, settling behavior, anti-alias filtering, and calibration against the complete manufacturer data before finalizing the PCB.

设计说明
Keep the isolated input and output networks physically separated so copper, solder mask, and exposed leads do not create an unintended low-impedance barrier path. Follow the manufacturer isolation-layout recommendations exactly, including component placement on only their respective domains. Do not route protective-earth or high-voltage conductors beneath the device unless the approved insulation system explicitly allows it.
Treat the two amplifier sides as separate circuit domains and verify every supply requirement from the manufacturer datasheet before adding bypass capacitors. The supplied source confirms the isolation mechanism but not supply voltage, current, sequencing, or grounding limits. In particular, do not connect grounds solely because they appear at the same schematic level; doing so can defeat the isolation function.
Do not equate the 750 V continuous isolation figure with unrestricted working voltage at every frequency, temperature, pollution degree, or overvoltage condition. The 0.3 uA leakage maximum applies specifically at 240 V RMS, 60 Hz, and the 60 kHz figure is signal bandwidth, not a guarantee of loop accuracy above that frequency. Confirm test conditions, derating rules, and application safety requirements from the complete datasheet.
Select RF and RIN only after checking the complete resistor tables and parasitic limits. The source text establishes VOUT/IIN = RF and VOUT/VIN = RF/RIN, but it does not provide resistor ranges, source-impedance restrictions, output drive capability, or tolerance curves. Place feedback and gain-setting parts close to their associated pins and provide filtering only after measuring the complete isolation path response.
合规信息
