8.2.2.1 Basic Setup

The basic setup of this true zero output amplifier is given in Figure 32. The LMP7701 op amp is configured as a voltage follower to demonstrate the output limitation, due to the saturation of the output stage. The negative power supply pin of the op amp can be connected to ground level or to the output of the negative bias generator, to demonstrate the VDSAT effect at the output voltage range.

The output voltage of the LMP7701 is converted to the digital domain using an ADC122S021. This is an 12-bit analog to digital converter with a serial data output. Data processing and graphical displaying is done with a computer. The negative power supply pin of the op amp can be connected to ground level or to the output of the negative bias generator, to demonstrate the effect at the output voltage range of the op amp.
