3 Description

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 highvoltage

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 AMC0380DQ1

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.
