The AMC1301DWVR from Texas Instruments is a precision isolated amplifier with a +/-250mV input voltage range optimized for current measurements using shunt resistors. The device features a fixed gain of 8.2V/V with excellent DC accuracy: +/-0.2mV offset error, +/-0.3% gain error, and 0.03% nonlinearity. The input circuitry is separated from the output by a reinforced isolation barrier certified to 7070Vpk per DIN EN IEC 60747-17 (VDE 0884-17) and 5000Vrms per UL1577, supporting a working voltage of up to 1000Vrms. The isolation barrier is highly resistant to magnetic interference and provides 15kV/us minimum common-mode transient immunity. Integrated diagnostic features include common-mode overvoltage detection and missing high-side supply voltage detection, simplifying system-level fault handling. Both the high-side and low-side operate from 3.0V to 5.5V, and the device is available in a wide-body 8-pin SOIC (DWV) package rated for -40 to 125 C.

The AMC1301DWVR operates as a precision isolated amplifier using capacitive isolation technology. Key subsystems include: (1) High-Side Input Stage – a differential amplifier with +/-250mV input range accepts signals directly from shunt resistors; the input is optimized for low voltage levels with high common-mode rejection; (2) Modulator – a sigma-delta modulator on the high-side converts the analog input to a digital bitstream; (3) Capacitive Isolation Barrier – two high-voltage capacitors transmit the digital bitstream across the isolation barrier; this barrier provides reinforced isolation up to 7070Vpk and is highly resistant to magnetic interference unlike optocouplers; (4) Demodulator – on the low side, a demodulator reconstructs the analog signal from the received bitstream; (5) Output Filter – an internal analog filter produces the differential output voltage centered at VDD2/2; (6) Diagnostic Circuit – monitors the high-side common-mode voltage and supply; a fault condition drives the differential output to a failsafe voltage level (-2.545V) that can be detected by the downstream ADC.
