This reference design focuses on high-side current measurement using a family of TI's voltage output current shunt monitors. It can be used for measuring high-side current in industrial applications, where the common-mode dynamics can drop below ground. Overall the design helps designers build Electromagnetic Compatibility (EMC) compliant circuitry around current shunt monitor devices while achieving high-accuracy current monitoring solutions in presence of wide range of common-mode voltages from -14V to +80V.
Features:
Wide common mode input range: -14V to 80V
Overvoltage protection: 45V
EFT protection up to 1KV as per IEC61000-4-4
>130dB CMRR for DC-10Hz
Overall accuracy better than 2%
70 µV offset and 1.4% gain error
