Description

  • Bipolar +/-10V analog output from a unipolar voltage output DAC. This unipolar to bipolar signal conditioning circuit uses an Op-Amp with negative feedback and three resistors in a modified summing amplifier configuration to generate high-voltage bipolar outputs from a generic single supply unipolar digital-to-analog converter (DAC). This design will take consideration for generating voltage outputs commonly used in industrial process control applications and for driving reactive loads such as long cables also common in industrial applications

Key Features

  • Number of Supplies
    Single
  • Supply Voltage
    5 V
