Texas Instruments AMC131M03-Q1

Description

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 energy-measurement-specific features, making the device 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.
