8.2 Typical Application

This section shows the measurement results of a true zero output amplifier application with an analog to digital converter (ADC) used as back-end. The biasing of the op amp can be done in two ways:

  • A single supply configuration
  • A single supply in combination with the LM7705, extending the negative supply from ground level to a fixed –0.23 Voltage.
