AMC130M03 16-Bit Isolated Delta-Sigma ADC Texas Instruments AMC130M03 16-Bit Isolated Delta-Sigma Analog-to-Digital Converter (ADC) is a precision, three-channel, data- and power-isolated, simultaneous-sampling, 16-bit, delta-sigma (ΔΣ), ADC. The AMC130M03 offers a wide dynamic range of energy-measurement-specific and low-power features for power metrology and energy metering applications. The ADC inputs can be directly interfaced with a shunt current sensor or a resistor-divider network because of the device's high input impedance.
