TIDA-00208, Single-Ended Signal Conditioning Circuit for Current and Voltage Measurement Using Fluxgate Sensors

TIDA-00208, Single-Ended Signal Conditioning Circuit for Current and Voltage Measurement Using Fluxgate Sensors. This design provides a 4-channel signal conditioning solution for single-ended SAR ADCs integrated into a microcontroller measuring motor current using fluxgate sensors. Also provided is an alternative measurement circuit with external SAR ADCs as well as circuits for high-speed overcurrent and earth fault detection. Proper 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
