TIDA-00499, Digital Fault Recorder AFE Using Differential Amplifiers and HS ADC Reference Design

TIDA-00499, Digital Fault Recorder AFE Using Differential Amplifiers and HS ADC Reference Design. While Digital Fault Recorders (DFR) can detect transients in 17/20 us at 60/50 Hz. This Design demonstrates the capturing of Digital Fault Recorder and 25 MHz. Both positive and negative transients (<=2kV peak) can be captured with varying resolution based on application need (12-14 bit resolution) and within 10% accuracy using a differential amplifier driving a high speed converter
