3 Description

The AMC130M03 is a precision three-channel, dataand

power-isolated, simultaneous-sampling, 16-bit,

delta-sigma (ΔΣ) analog-to-digital converter (ADC).

The AMC130M03 offers wide dynamic range, low

power, and energy-measurement-specific features,

making the device 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 AMC130M03 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 V 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 AMC130M03

an excellent choice for polyphase energy metering

applications using shunt current sensors.
