The AMC0100R is a precision, galvanically isolated amplifier with a ±250mV differential input, and single-ended, ratiometric output. The input is optimized for direct connection to a shunt resistor or other low-impedance signal source.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels or noise sensitive circuitry from power stages. The isolation barrier supports a working voltage up to 200VRMS / 280VDC and transient over voltages up to 570VRMS / 800VDC (60s).

The AMC0100R outputs a single-ended signal proportional to the input voltage. The full-scale output is set by the voltage applied to the REFIN pin. The output of the AMC0100R is designed to connect directly to the input of an ADC. Connect REFIN to the same reference voltage as the ADC to match the dynamic input voltage range of the ADC.

The AMC0100R is available in a 8-pin, 0.65mm pitch VSON package and is fully specified over the temperature range from –40°C to +125°C.
