Texas Instruments AMC3311-Q1

Beschreibung

The AMC3311-Q1 is a precision, isolated amplifier with a fully integrated, isolated DC/DC converter that allows single-supply operation from the low-side of the device. The reinforced capacitive isolation barrier is highly resistant to magnetic interference, is certified according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577, and supports a working voltage of up to1200 VRMS.
