7.3.2 Basic Amplifier Configurations

As with other single-supply operational amplifiers, the OPA365-Q1 may be operated with either a single supply or dual supplies (see Figure 7-1). A typical dual-supply connection is shown in Figure 7-1, which is accompanied by a single-supply connection. The OPA365-Q1 device is configured as a basic inverting amplifier with a gain of −10 V/V. The dual-supply connection has an output voltage centered on zero, while the single− supply connection has an output centered on the common-mode voltage VCM. For the circuit shown, this voltage is 1.5 V, but may be any value within the common-mode input voltage range. The OPA365-Q1 VCM range extends 100 mV beyond the power-supply rails.

Figure 7-2 shows a single-supply, electret microphone application where VCM is provided by a resistive divider. The divider also provides the bias voltage for the electret element.
