AMC1302 Datasheet Reinforced Isolated Amplifier

Manufacturer: Texas Instruments

Overview: AMC1302 SBAS812D – JUNE 2018 – REVISED JUNE 2021 AMC1302 Precision, ±50-mV Input, Reinforced Isolated Amplifier.

General Description

The AMC1302 is a precision, isolated amplifier with an output separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference.

This barrier is certified to provide reinforced galvanic isolation of up to 5 kVRMS according to VDE V 0884-11 and UL1577, and supports a working voltage of up to 1.5 kVRMS.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from hazardous voltages and damage.
