The AMC0380D-Q1 is a precision, galvanically isolated amplifier with a high-voltage AC, 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 of up to 5kVRMS (60s).

The AMC0380D-Q1 outputs a differential signal that is proportional to the input voltage. The differential output is insensitive to ground shifts and enables routing the output signal over long distances.

The AMC0380D-Q1 is available in three linear input voltage ranges: ±400V, ±600V, and ±1000V. With an integrated precision resistive divider, the AMC0380D-Q1 achieves better than 1% accuracy over the full temperature range, including lifetime drift.

The AMC0380D-Q1 is available in a 15-pin, 0.65mm pitch SSOP package and is fully specified over the temperature range from –40°C to +125°C.
