The AMC131M03-Q1 is a precision three-channel, isolated, simultaneous-sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC). The AMC131M03-Q1 offers wide dynamic range, low power, and is designed for isolated voltage and current measurements in automotive 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-Q1 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 lower-voltage parts from damage.
