Level Translation: Dual to Single Supply Amp, ±15V to 5V


Design files


Translating a ±15V signal to a single supply 5V signal for use with an ADC is a common circuit requirement.  This Dual Supply to Single Supply Amplifier circuit design translates a ±15V signal to a 0V to 5V signal.  The output of this design will not be outside of 0-5V regardless of power supply sequencing or other transient conditions.

  • Shift a ±15V supply to a single 5V or 3V supply
  • Protection from power supply sequencing issues
