The AMC131M03 is a precision, three-channel, data- and power-isolated, simultaneous-sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC). The AMC131M03 offers wide dynamic range, low power, and energy-measurement-specific features designed for energy metering and power metrology applications. The ADC inputs can be directly interfaced to a resistor-divider network or a shunt current sensor because of the device high input impedance.

The AMC131M03 features a fully integrated isolated DC/DC converter that allows single-supply operation from the low-side of the device. The reinforced capacitive isolation barrier is certified according to VDE 0884-17 and UL1577. This isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects lower-voltage parts from damage, making the AMC131M03 an excellent choice for polyphase energy metering applications using shunt current sensors.
