ISO113 Visão geral
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.

Aplicações típicas
ISO113 é adequado para 7 aplicaçãos: Industrial Sensor Signal Conditioning, Power Converter Feedback Isolation, High-Voltage Equipment Monitoring, Data Acquisition Systems, Medical Instrument Signal Conditioning, Laboratory and Process Measurement, Legacy Industrial Control Interfaces.
Industrial Sensor Signal Conditioning
The ISO113 fits industrial sensor interfaces that need to transfer a measurement across an isolation barrier. Its 1500Vrms continuous AC barrier rating and internally powered output side can reduce the need for a separate isolated output supply. The 10V to 18V supply range and 1.5V/µs slew rate support instrumentation systems, while the wide barrier spacing supports careful PCB layout. Confirm the input common-mode range and sensor output amplitude against the manufacturer datasheet before implementation.
Recomendado
Power Converter Feedback Isolation
The ISO113 can be used to isolate feedback signals in power-converter and power-supply monitoring circuits. Its internally powered output side simplifies the isolated signal path, while the 1500Vrms continuous AC barrier rating supports designs with a substantial potential difference between input and output domains. The engineer must still verify isolation topology, loop stability, input range, and the final system creepage and clearance requirements.
Recomendado
High-Voltage Equipment Monitoring
The ISO113 is appropriate for monitoring circuits that must safely transfer a measurement away from high-voltage equipment. The 1500Vrms continuous AC barrier rating, low barrier capacitance, and 100% barrier breakdown testing are relevant to reinforced separation in instrumentation equipment. The component is not a standalone safety approval, so the final product must meet its applicable insulation, clearance, creepage, and fault-safety requirements.
Recomendado
Data Acquisition Systems
The ISO113 can isolate analog channels before they reach a data-acquisition front end, helping prevent ground-current coupling between field instrumentation and measurement electronics. Its internally powered output and 16-CDIP through-hole package are useful for legacy or industrial acquisition boards with adequate board spacing. The 10V to 18V supply requirement and 1.5V/µs slew rate should be checked against the acquisition bandwidth and output settling requirements.
Recomendado
Medical Instrument Signal Conditioning
The ISO113 may be evaluated for medical instrumentation signal paths where patient-side and equipment-side circuits require isolation. Its 1500Vrms continuous AC barrier rating and low barrier capacitance are useful attributes, but the supplied data does not claim medical certification or AEC-Q100 qualification. Medical use therefore requires a system-level risk assessment, applicable standards review, validation, and confirmation that the final device satisfies the required isolation and leakage limits.
Recomendado
Laboratory and Process Measurement
The ISO113 supports laboratory and process-measurement designs where a sensor, transducer, or control signal must cross an electrically noisy or high-potential boundary. The single-channel output isolation amplifier structure, wide barrier spacing, and through-hole package make it suitable for equipment with planned isolation creepage and clearance. Designers should use low-leakage input networks, provide the specified supply range, and verify accuracy and stability in the complete analog chain.
Recomendado
Legacy Industrial Control Interfaces
The ISO113 is suitable for maintaining or repairing legacy industrial control equipment that uses a 16-CDIP isolation-amplifier footprint. Its through-hole double-wide DIP package supports hand installation and socket or PCB compatibility, while the internal isolated output power can simplify retrofit designs. Before substitution, confirm the exact pinout, supply polarity, isolation rating, bandwidth, and component availability because the supplied data does not establish a complete second-source list.

Notas de projeto
Maintain the manufacturer-specified creepage and clearance around the 1500Vrms isolation barrier. Keep copper, solder mask, test pads, and mechanical hardware from bridging the input-side and output-side regions. The double-wide 16-CDIP package provides physical separation, but PCB routing must preserve that separation rather than treating the DIP body outline alone as sufficient insulation.
Provide a supply within the verified 10V to 18V ISO113 range and place bypass capacitors close to the device power pins according to the manufacturer application guidance. Check startup behavior and supply noise at the isolated output. Because the device is internally powered, the output-side supply arrangement still requires correct grounding and decoupling; internal isolation power does not remove the need for system-level layout discipline.
Do not substitute a generic digital isolator or a different-package isolation amplifier as a drop-in replacement. ISO113 is a 16-CDIP output isolation amplifier with a 1500Vrms continuous AC barrier rating; IL612-3E, for example, is listed as an 8-pin surface-mount digital isolator. Confirm pinout, supply range, isolation rating, bandwidth, accuracy, and package footprint against the full datasheet before any replacement decision.
Keep the isolated input loop small and use low-leakage, low-tolerance feedback and bias components where the measurement accuracy is important. The ISO113 datasheet highlights low barrier capacitance to minimize AC leakage currents, but external PCB leakage, contamination, and grounding still affect system performance. Validate common-mode range and leakage in the final instrumentation enclosure, especially when the barrier operates near its continuous rating.
Informações de conformidade
RoHS compliance is stated in the verified distributor product data. No REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification claim appears in the supplied data. The 100% barrier breakdown testing statement refers to UL1244 test methods and does not constitute a complete product certification.
