ISO122U

Overview

The ISO122U is a precision isolation amplifier from Texas Instruments, housed in an 8-pin SOIC package. It features a 50 kHz bandwidth and 140 dB common-mode rejection ratio. The device operates on dual supply voltages ranging from ±4.5 V to ±18 V, with a maximum input offset voltage of 20 mV. It provides galvanic isolation up to 1500 Vrms and functions within a temperature range of -25°C to +85°C.

Feature Summary

Provides high-precision signal amplification with low input offset voltage for accurate measurements.
Ensures electrical safety through robust capacitive galvanic isolation between input and output circuits.
Delivers high common-mode rejection capability to suppress noise in noisy industrial environments.

Applications

Industrial process control systems requiring isolated sensor signal conditioning
Medical equipment needing patient isolation for safety compliance
Power monitoring applications involving high-voltage differential measurements

Procurement Notes

Verify the specific suffix (e.g., U, UE4) against the datasheet to confirm pinout and packaging details. Ensure the selected variant matches the required operating temperature range and isolation voltage ratings for the target application environment.

Selection Notes

Select this component when high accuracy and moderate bandwidth are required in isolated analog front ends. Compare gain error specifications against other ISO12x series variants if tighter tolerance is needed. Confirm that the SOIC-8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISO12x family of precision isolation amplifiers designed for cost-effective solutions. It shares architectural similarities with the ISO124 but offers distinct performance characteristics regarding input offset voltage and power consumption suitable for general-purpose isolation tasks.
