This absolute value circuit can turn alternating current (AC) signals to single polarity signals. This circuit functions with limited distortion for ±10-V input signals at frequencies up to 50kHz and for signals as small as ±25mV at frequencies up to 1kHz.

  • 30V Split supply with ground reference 
  • Input: +/-25mV to +/-10V 
  • Output: 25mV to 10V
