Precision 1500V-input reinforced isolated amplifier with differential output

The AMC0381D 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 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

AMC0381D is available in three linear input voltage ranges:

600V, 1000V, and 1600V. With an integrated precision resistive divider, the AMC0381D achieves better than 1% accuracy over the full temperature

range, including lifetime drift.

The AMC0381D is available in a 15-pin, 0.65mm pitch SSOP package. The

device is fully specified over the temperature range from –40°C to +125°C.
