This design provides a 4-channel signal conditioning solution for differential ADCs integrated into a microcontroller measuring motor current using fluxgate sensors. Also provided is an alternative measurement circuit with external differential SAR ADCs as well as circuits for high-speed overcurrent and earth fault detection. Proper differential signal conditioning improves noise immunity on critical current measurements in motor drives. This reference design can help increase the effective resolution of the analog-to-digital conversion: improving motor drive efficiency.
