Overview

This verified reference design implements isolated current sensing data acqusition based on AMC1304M25 isolated delta-sigma (ΔΣ) modulator and TMS320F28377D microcontroller. This design was made for shunt-based current measurement applications which require excellent galvanic isolation and accuracy, such as industrial motor drives, photovoltaic inverters and energy metering. It is capable of measuring load currents from -10 A to +10 A with better than 0.3% uncalibrated accuracy, and it also provides dual functionality of a high resolution channel and an additional over-current or short-circuit detection channel. Design functionality and performance were verified against the circuit design goals by fabricating three PCBs and measuring results for DC and AC input signals.

Features

Verified design contains theory, component selection, TINA-TI simulation, measured results, PCB layout and modifications
Galvanically-isolated current sensing
16-bit output at 78.1 kSPS
±10 A at < 0.3% (uncalibrated accuracy)
78-dB SNR (min)
