The AMC0x30D-Q1 is a precision, galvanically isolated amplifier with a ±1V, high-impedance input, and fixed-gain differential output. 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 (DWV package) and basic isolation up to 3kVRMS (D package) (60s).

The AMC0x30D-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.

The AMC0x30D-Q1 comes in 8-pin, wide- and narrow-body SOIC packages, and is fully specified over the temperature range from –40°C to +125°C.
