ISO100AP 개요
An isolation amplifier is an analog signal-conditioning component that transfers a differential input to an output while providing galvanic isolation between input and output grounds. In the signal-chain hierarchy, an isolation amplifier sits between sensors, transducers, and amplifiers and downstream data converters or measurement systems. Optocoupling inside the ISO100AP reduces conductive coupling between the two sides, helping protect sensitive equipment from high common-mode voltage and ground-potential hazards.
The available feature data highlights simple feedback-set gain relationships, 100% tested 750 V continuous isolation, ultra-low leakage of 0.3 µA maximum at 240 V/60 Hz, and wide bandwidth. For a current input, the output relationship is VOUT/IIN = RF; for a voltage input, the relationship is VOUT/VIN = RF/RIN. These relationships allow an engineer to select external resistors for the desired conversion gain while retaining the device's isolated signal path.
The ISO100AP is suited to industrial current sensing, medical monitoring, laboratory instrumentation, data acquisition, and power-system measurement where the input and output domains must remain electrically separated. The 18-CDIP package is appropriate for through-hole PCB construction rather than compact surface-mount designs. Because the verified data does not provide the complete electrical table or a complete pin map, designers should consult the manufacturer datasheet before finalizing supply voltages, gain accuracy, common-mode range, slew rate, and isolation ratings.
A key design consideration is to keep the input-side and output-side return paths separate and to place the external gain-setting resistors close to their associated pins. Verify the required bandwidth and input common-mode range against the 60 kHz device description. The ISO100AP should be selected when optical isolation and the verified 750 V continuous isolation rating justify the through-hole package and external resistor configuration.

일반적인 애플리케이션
ISO100AP 적합 용도: 6 애플리케이션s: Industrial Current Sensing, Medical Monitoring, Laboratory Instrumentation, Data Acquisition Systems, Power-System Monitoring, Industrial Sensor Interfaces.
Industrial Current Sensing
ISO100AP fits current-measurement systems that require an isolated analog signal path between a high-voltage or high-common-mode current loop and downstream control electronics. Its verified 1-channel optically coupled architecture, 60 kHz bandwidth, and current-input relationship of VOUT/IIN = RF allow the conversion ratio to be set with an external feedback resistor. The 750 V continuous isolation rating can help separate the sensed domain, but the designer must verify the actual working voltage, common-mode range, input current range, output swing, and creepage requirements against the complete datasheet. The 18-CDIP through-hole package favors industrial control boards where field wiring and serviceability matter more than compact area.
추천
Medical Monitoring
ISO100AP can support isolated acquisition front ends in medical and diagnostic equipment when the measured signal requires separation from the host system. The optically coupled isolation barrier and verified 750 V continuous isolation are useful design attributes for protecting sensitive electronics from patient-side or instrument-side connections. Its 60 kHz bandwidth is appropriate for many low-frequency physiological signals, while the exact application suitability depends on leakage, accuracy, common-mode range, supply voltage, and safety requirements that are not fully present in the supplied snippets. Use the manufacturer application guidance and validate the complete isolation system rather than treating the component rating alone as regulatory approval.
추천
Laboratory Instrumentation
ISO100AP is suitable for laboratory measurement systems that need to transfer analog sensor or transducer signals across a galvanic barrier. Its verified 60 kHz bandwidth supports many precision instrumentation signals, and external RF and RIN resistors implement the documented gain relationships for current or voltage inputs. The optically coupled structure helps prevent ground currents from disturbing sensitive source circuits. For laboratory use, verify input bias, offset, noise, linearity, temperature behavior, supply requirements, and output reference because those values are not included in the supplied search data. The 18-CDIP package is practical for bench-style and legacy instrument platforms with through-hole construction.
추천
Data Acquisition Systems
ISO100AP can be used at the input boundary of a data-acquisition system where a transducer must remain electrically isolated from the ADC, computer, or control ground. The verified one-channel optically coupled architecture carries the analog measurement signal while the verified 750 V continuous isolation rating supports a stronger separation strategy than a conventional grounded amplifier. The 60 kHz listed bandwidth is suitable for many sensor and process signals, provided the complete input and output ranges are respected. A practical design places external gain-setting resistors near the associated pins, maintains controlled grounding on each side, and uses an ADC such as ADS8320E/2K5 only after checking the isolation amplifier's output swing and acquisition bandwidth.
추천
Power-System Monitoring
ISO100AP may be applied to power-system monitoring when a current or voltage from an isolated sensing stage must be transferred to a controller or recorder. Its verified continuous isolation of 750 V and optically coupled signal transfer provide useful separation functions, while the 60 kHz bandwidth is adequate for many fundamental-frequency and slower transient measurements. The component does not replace a dedicated high-voltage safety barrier, surge protection network, or appropriately rated sensing resistor. Engineers should verify maximum working voltage, transient limits, creepage, clearance, isolation impedance, and input common-mode requirements in the full manufacturer documentation before connecting the device to hazardous power circuits.
추천
Industrial Sensor Interfaces
ISO100AP is appropriate for isolated sensor interfaces where a transducer shares a noisy industrial ground or where the measurement must be transferred into a separate control domain. Its current and voltage input modes, resistor-programmed transfer relationships, and optically coupled isolation provide a flexible analog front-end building block. The verified 60 kHz bandwidth limits the usable signal class to designs that do not require higher-frequency response. Because the supplied data omits the complete electrical table, verify offset, drift, linearity, input impedance, output impedance, supply voltage, and temperature range before production. The through-hole CDIP package also allows inspection and rework in legacy industrial equipment.

설계 노트
Keep the input-side and output-side copper regions separated according to the ISO100AP datasheet isolation layout. Do not route signal or return copper across the isolation boundary except where the circuit architecture explicitly requires it. Preserve creepage and clearance around the 18-CDIP leads, use adequate board-cleanliness practices, and check the final PCB against the verified 750 V continuous isolation rating. This is a layout recommendation, not a substitute for the complete safety and isolation calculations.
Select RF and RIN resistors using the documented relationships VOUT/IIN = RF and VOUT/VIN = RF/RIN. Place the external gain-setting components close to the associated ISO100AP pins to reduce parasitic resistance, capacitance, and noise pickup. Because the verified data gives a 60 kHz listed bandwidth but does not provide the complete gain-bandwidth or output-swing tables, prototype the selected resistor values against the required signal amplitude and measurement accuracy.
Do not treat the ISO100AP isolation rating as permission to exceed the unprovided operating-voltage, common-mode, transient, or safety limits. Confirm supply voltage, input range, output swing, temperature range, isolation impedance, and recommended external components in the official datasheet. For a replacement, check every pin and suffix-specific function; the supplied ISO100CP and ISO100BP comparison snippets do not establish complete drop-in equivalence.
The verified distributor pricing snapshot shows a reference unit price of $142.9045, but it is not an XAIPART quotation and may change with quantity, inventory, and market conditions. For procurement, request a dated quote, confirm authorized sourcing, verify packaging and lot status, and do not substitute a merely similar ISO100-family part without a complete pin and electrical comparison.
규정 준수 정보
The verified search data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The 750 V continuous isolation and 100% breakdown-test statements are technical feature descriptions, not compliance certifications.
