The AMC4330R is a precision, galvanically isolated amplifier with a fully integrated, isolated DC/DC converter that allows single-supply operation from the low-side of the device. The DC/DC converter is capable of sourcing an external current of up to 8mA to power additional device (example:AMC0300D, AMC23C12) on the high side. 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.

The AMC4330R 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 AMC4330R 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 AMC4330R device comes in 20-pin, wide-body SOIC package, and is fully specified over the temperature range from –40°C to +125°C.
