8.1.1 Basic Amplifier Configurations

The OPAx376-Q1 family is unity-gain stable. It does not exhibit output phase inversion when the input is overdriven. A typical single-supply connection is shown in Figure 8-1. The OPA376-Q1 is 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 in Figure 8-1, this voltage is 2.5 V, but may be any value within the common-mode input voltage range.
