ISO113B Présentation
An isolation amplifier is a signal-conditioning amplifier with a galvanically isolated signal path. Its hierarchy is isolation amplifier, instrumentation amplifier, amplifier, analog IC, and semiconductor. This category protects measurement equipment and personnel from common-mode voltage while preserving a defined relationship between an input signal and its isolated output. Unlike a conventional differential amplifier, the ISO113B deliberately separates the input-side and output-side power domains through an isolation barrier.
The primary verified features include self-contained isolated signal and output power, a 1500 Vrms continuous AC barrier rating, and a small double-wide side-braze DIP outline. Its 20 kHz bandwidth makes it suitable for slow industrial-control, power-system, and instrumentation signals rather than high-speed communications. The internally powered output eliminates the need for a separate isolated output supply in circuits designed around this device.
The ISO113B belongs to the ISO113 low-cost, high-voltage, internally powered output isolation-amplifier family. The B suffix is retained exactly as supplied; the verified data does not state the meaning of that suffix or its grade. Consult the manufacturer datasheet before production use because detailed gain, input range, isolation capacitance, timing, temperature limits, and supply requirements were not included in the supplied records.
Typical applications include isolated current measurement, motor-drive sensing, industrial data acquisition, power-supply monitoring, and high-voltage equipment interfaces. In each case, the amplifier can bridge a measurement domain electrically separated from the processing side. Designers must still preserve the specified isolation creepage, clearance, package geometry, bypass requirements, and common-mode limits.
The key design consideration is that the CDIP-16 package is through-hole and larger than modern surface-mount isolation packages. Board space, lead spacing, assembly tooling, and isolation-region layout must therefore be planned around the verified 0.600-inch side-braze DIP outline rather than assumed from a surface-mount library.
This page consolidates the supplied manufacturer-family description, distributor identification, package data, sourcing links, and cross-reference results. It also distinguishes verified facts from parameters that require the complete manufacturer datasheet, avoiding unsupported guesses while supporting component selection and procurement.

Applications typiques
ISO113B convient pour 6 applications: Industrial Process Signal Isolation, Motor Drive Feedback Monitoring, Isolated Power-Supply Feedback, High-Voltage Test and Measurement, Current-Sensor Signal Conditioning, Legacy Data-Acquisition Backplane.
Industrial Process Signal Isolation
The ISO113B fits slow industrial process signals that must cross from a high-voltage field side to a safer controller side. Its verified 20 kHz bandwidth is appropriate for many temperature, pressure, position, and supervisory-control signals, while the 1500 Vrms continuous AC barrier provides a defined isolation boundary. The internally powered output can simplify the isolated output side compared with a design requiring external isolated power. The engineer must still confirm input range, gain, output swing, and common-mode limits in the full manufacturer datasheet.
Recommandé
Motor Drive Feedback Monitoring
The ISO113B can monitor feedback or command information across the isolation boundary of a motor-drive or power-conversion system. Its verified 20 kHz bandwidth suits slower control and supervisory signals rather than high-bandwidth gate-drive paths, and its 1500 Vrms continuous AC barrier supports applications requiring substantial galvanic separation. Use it for a defined analog feedback channel rather than assuming it can drive high-power switching devices directly. Common-mode voltage, input offset, gain accuracy, and output-drive data must be verified before implementation.
Recommandé
Isolated Power-Supply Feedback
The ISO113B is suitable for transferring power-supply feedback information when the measured domain contains substantial voltage relative to the control system. The verified 1500 Vrms continuous AC barrier defines the isolation function, while the internally powered output helps keep the receiving side electrically independent. The device should be selected only after checking the complete feedback signal range and permitted common-mode level. Because its 20 kHz bandwidth is modest, compensation-loop requirements must be analyzed rather than assuming it can improve high-frequency dynamic response.
Recommandé
High-Voltage Test and Measurement
The ISO113B can serve as an isolation interface in test and measurement equipment where a low-level analog signal must be referenced to a hazardous or high-voltage node. Its verified 1.5 kVrms continuous AC barrier and 20 kHz bandwidth align with many metering and laboratory signal paths rather than communications links. Through-hole CDIP construction supports rugged legacy instrument architectures. The complete safety design must still assess creepage, clearance, insulation type, working voltage, and applicable standards; those parameters are not present in the supplied excerpts.
Recommandé
Current-Sensor Signal Conditioning
The ISO113B can condition a suitably scaled current-sensor output while electrically separating it from the measuring or control electronics. The 20 kHz bandwidth can accommodate many current-measurement loops, and the internally powered output avoids requiring a separate output-side isolated supply. Compatibility depends on the sensor technology, shunt or Hall-sensor output range, isolation topology, and common-mode voltage. Input offset, gain, bandwidth stability, and output swing were not supplied, so calibration and worst-case error budgets must be based on the complete manufacturer datasheet.
Recommandé
Legacy Data-Acquisition Backplane
The ISO113B is useful when maintaining or cloning a legacy data-acquisition backplane designed around its 16-terminal ceramic DIP footprint and internally powered isolation topology. The through-hole package supports hand installation and conventional through-hole assembly, while the 1500 Vrms barrier separates selected measurement channels. It is not a universal substitute for modern digital isolators or high-speed isolated converters. Before purchasing, compare the original schematic, pin names, supply arrangement, isolation-side grounding, bandwidth, and calibration method to the official ISO113-family documentation.

Notes de conception
Keep the ISO113B isolation region free of copper, traces, test fixtures, and fasteners unless the completed safety design explicitly permits them. Although the verified package is a 16-CDIP with a 0.600-inch body width, the available excerpts do not provide pin functions, creepage, clearance, or pad dimensions. Copy the official land pattern and isolation dimensions from the manufacturer datasheet rather than generating them from a generic DIP footprint. Verify creepage and clearance against the actual working voltage and applicable safety requirements.
Treat the internally powered output as a device feature, not as permission to omit all bypassing or grounding. The supplied records identify self-contained isolated signal and output power but do not provide pin voltages, capacitor values, supply current, or startup limits. Before layout, obtain the complete ISO113-family datasheet and reproduce its recommended supply connections and bypass network. Maintain separate input-side and output-side return domains so unintended current cannot bypass the isolation barrier.
Design the analog path around the verified 20 kHz bandwidth rather than an assumed wider bandwidth. Place input and output filtering close to the device, use stable gain-setting components if the architecture requires them, and account for source impedance, offset, noise, and settling. Exact gain and input-range values are absent from the supplied records, so resistor values and capacitor selection cannot be finalized here. Validate the complete channel with the intended sensor, cable, grounding, and downstream converter.
Do not treat ISO121BG, ISO120SG, or ISO164P as drop-in replacements based only on comparison-page appearances. The supplied metadata does not verify a shared 16-CDIP pinout, electrical limits, or barrier rating for those parts. Before substitution, compare every terminal, input range, gain, bandwidth, supply arrangement, output swing, isolation capacitance, package drawing, and lifecycle status. A functional isolation amplifier with a different package or pinout requires PCB redesign and fresh validation.
Start thermal review with actual measured or calculated dissipation rather than assuming the wide ceramic package eliminates heat concerns. The supplied excerpts do not contain supply voltage, quiescent current, output drive, thermal resistance, or maximum junction temperature. Those values must be obtained from the official datasheet, and estimated dissipation must be checked against the permitted temperature grade. Through-hole ceramic construction helps mechanical robustness but does not guarantee unlimited power dissipation or temperature rise.
Informations de conformité
The supplied web results do not provide ISO113B-specific compliance declarations. Compliance must be confirmed from the current manufacturer documentation or authorized distributor records; no status was inferred.
