3 Description

The AMC131M01 is a precision, single-channel,

data- and power-isolated, 24-bit, delta-sigma (ΔΣ),

analog-to-digital converter (ADC). The AMC131M01

offers wide dynamic range, low power, and energymeasurement-

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 AMC131M01 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 lowervoltage

parts from damage, making the AMC131M01

an excellent choice for polyphase energy metering

applications using shunt current sensors.
