Description

  • RMS Current Measurement for Quartz Crystals Design Circuit. Op-Amps A1-A4 furnish gain of > 200,000, permitting sub-uA crystal current measurement. The LTC1563-2 bandpass filter smooths residual noise while providing unity gain at 32.768kHz. The LTC1968 RMS-to-DC converter supplies RMS calibrated output
