The AMC4311D is a precision, galvanically isolated amplifier with a fully integrated, isolated DC/DC converter that allows single-supply operation from the low-side of the device. The DC/DC converter is capable of sourcing an external current of up to 8mA to power additional device (example: AMC0300D, AMC23C12) on the high side. The high-impedance input is optimized for connection to a high-impedance resistive divider or other voltage signal source with high output resistance.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation up to 5kVRMS.

The AMC4311D outputs a differential signal proportional to the input voltage. The differential output is insensitive to ground shifts and enables routing the output signal over long distances.

The AMC4311D device comes in 20-pin, wide-body SOIC package, and is fully specified over the temperature range from –40°C to +125°C.
