Description

The TIDA-00753 reference design demonstrates high accuracy wide range AC current measurement for a three phase motor using the INA199 zero drift current shunt monitor. The design also has low power consumption of 25mW for Gain stage of 200 as compared to a discrete solution. The design footprint and BOM cost is much smaller than a discrete solution due to the integrated high precision resistors inside the INA199.

Features
  • 0.5 % Accuracy (Uncalibrated)  for 10 to 100 % of Full Scale Primary Current
  • Power Consumption of 25 mW for Gain Stage
  • Small Footprint no need of External Resistors for Amplfication
