Transient and Digital Fault Recorder AFE Using Differential Amplifiers and HS ADC Reference Design
Description
While Digital Fault Recorders (DFRs) can detect transients in 17/20 μs at 60/50 Hz: transient recorders capture disturbances that can peak and decay well within a microsecond. This reference design demonstrates the capturing of transient inputs at up to 1 MHz for DFR and 25 MHz for transient tecorders. Both positive and negative transients (
Features
- Transient recording from 10 MHz to 25 Mhz (> 166:000 samples/cycle)DFR of up to 1 MHzDifferential amplifier front end to interface transient inputs to differential ADCMeasurement range: capture input transient from 250-V to 2-kV peak: 1.2/50 usMeasurement sensitivity (10% to 100% of input voltage range): ±20 V (resolution) for 2-kV peakMeasurement accuracy (10% to 100% of input voltage range): Tested for surge immunity as per IEC61000-4-5 up to 4 kV with 42-Ω impedance
