AMC3301 Datasheet Reinforced Isolated Amplifier

Manufacturer: Texas Instruments

Overview: www.ti.com SBAS917B – AUGUST 2019 – REVISEAADMMMCCAY332330002111 SBAS917B – AUGUST 2019 – REVISED MAY 2021 AMC3301 Precision, ±250-mV Input, Reinforced Isolated Amplifier With Integrated DC/DC Converter.

General Description

The AMC3301 is a precision, isolated amplifier optimized for shunt-based current measurements.

The fully integrated, isolated DC/DC converter allows single-supply operation from the low-side of the device, which makes the device a unique solution for space-constrained applications.

The reinforced capacitive isolation barrier is certified according to VDE V 0884-11 and UL1577 and supports a working voltage of up to 1.2 kVRMS.
