The AMC3311 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 to 1200 V RMS.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from voltage levels that can cause electrical damage and are potentially harmful to an operator.

The input of the AMC3311 is optimized for direct connection to high-impedance resistive dividers that are typically used for sensing high voltages. The integrated isolated DC/DC converter allows measurement of non-ground-referenced signals and makes the device a unique solution for noisy, space-constrained applications. The high DC accuracy and low temperature drift support accurate voltage monitoring and control.

The AMC3311 is offered in a wide-body, 16-pin SOIC package, and is specified over the temperature range of –40°C to +125°C.
