The AMC0381D-Q1 is a precision, galvanically isolated amplifier with a high-voltage DC, high impedance input, and fixed-gain differential output. The input is designed to connect directly to a high-voltage signal source.

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 and is certified to provide reinforced isolation up to 5kVRMS (60s).

The AMC0381D-Q1 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.

With an integrated precision resistive divider, the AMC0381D-Q1 achieves better than 1% accuracy over the full temperature range, including lifetime drift.

The AMC0381D-Q1 is available in a 15-pin, 0.65mm pitch and a smaller, 20-pin, 0.5mm pitch SSOP package. The device is fully specified over the temperature range from –40°C to +125°C.
