Reference Design for Interfacing Current Output Hall Sensors and CTs with Differential ADC/MCU

Description

This reference design provides interfacing current output Hall sensors and current transformers to differential ADC (standalone and integrated into MCU). The differential signal conditioning circuit is designed to measure motor current with an accuracy of ±0.5% across operating temperature range from -25 °C to 75 °C. The output common-mode voltage of the differential amplifier can be selected to either 1.25 V or 2.5 V.

Features
  • On-board current-output Hall sensor to measure nominal current up to 25-A RMSCurrent measurement accuracy of 0.5%Common reference solution for interfacing both CT and current output hall sensor with pseudo-differential ADC/MCUSelectable output common-mode voltage for the differential amplifierProvision to evaluate with Delfino F2837x control cardProvision to evaluate with external ADC (ADS8354) for interfacing with motor controller
