Single-ended input to differential output circuit




This circuit converts a single ended input of 0.1 V to 2.4 V into a differential output of ±2.3 V on a single 2.7-V supply. The input and output ranges can be scaled as necessary as long as the op amp input commonmode range and output swing limits are met.
  • Input: Vi = 0.1 V to 2.4 V
  • Output: Vo = -2.3 V to 2.3 V
  • Supply:
    • Vcc = 2.7 V
    • Vee = 0 V
    • Vref = 2.5 V
