The AMC1200C is a precision, galvanically isolated amplifier with a ±250mV, differential input and differential 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. The isolation barrier is highly resistant to magnetic interference. This barrier is certified to provide basic isolation up to 5kVRMS (60s).
The AMC1200C 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 AMC1200C comes in 8-pin, wide-body SOIC and SOP packages. The device is fully specified over the temperature range from –40°C to +125°C.
