- TIDA-00738, Extended Current and Voltage Measurement Using Shunts for Protection Relays Reference Design. The TIDA-00738 design demonstrates a unique approach for extending the current measurement range using a single shunt and voltage measurement using AMC1304Mx5 Isolated Delta-Sigma modulator. With careful selection of a low value shunt resistor that minimizes power dissipation, a front end amplifier with low noise and by introducing two gain paths, both upper and lower current limit is extended. Accuracy of < 0.5 % for both current and voltage measurement is achieved by interfacing the modulator output to AM437x host processor which performs the Sinc3 filtering
