Description
- TIPD165, Isolated, Shunt-Based Current Sensing Reference Design. This Verified Design implements an isolated current sensing data acquisition solution based on the AMC1304M25 isolated delta-sigma modulator and a TMS320F28377D microcontroller. This circuit was designed 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
