AMC1303E0520DWV

ADCs/DACs - Special Purpose Overview

The AMC1303E0520DWV is a precision isolated delta-sigma modulator from Texas Instruments, designed for high-accuracy current sensing applications. It features a reinforced capacitive isolation barrier with a 5 kVrms insulation voltage rating. The device accepts a differential input signal range of ±50 mV and provides a fixed gain of 20 V/V. It operates on a single supply voltage between 2.7 V and 5.5 V, consuming typical power suitable for industrial environments. The output is a CMOS-compatible serial bitstream sampled at 78 kSPS, intended for connection to external sigma-delta ADCs.

ADCs/DACs - Special Purpose Part Context

This component belongs to the AMC1303x family of isolated delta-sigma modulators. Variants within this series differ primarily by input voltage range (±50 mV or ±250 mV) and gain settings (10 V/V or 20 V/V). The E0520 suffix specifically denotes the ±50 mV input and 20 V/V gain configuration, distinguishing it from other models like the AMC1303E2520DWVR which handles larger input signals.

ADCs/DACs - Special Purpose Replacement Considerations

Compatible alternatives include other members of the AMC1303x family such as the AMC1303M0520DWVR or AMC1303E2520DWVR, provided the input signal amplitude matches the specific variant's range. Designers must verify that the external sigma-delta ADC supports the 78 kSPS output rate and CMOS logic levels.
