8.1.2 Basic Amplifier Configurations

The OPAx325 are unity-gain stable. The devices do not exhibit output phase inversion when the input is overdriven. A typical single-supply connection is shown in Figure 44. The OPAx325 are configured as a basic inverting amplifier with a gain of –10 V/V. This single-supply connection has an output centered on the common-mode voltage, VCM. For the circuit shown, this voltage is 2.5 V, but can be any value within the common-mode input voltage range.
