Three-channel, simultaneous-sampling 24-bit isolated delta-sigma ADC

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.
