9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

9.1.1 Amplifier Gain Configurations

The OPA810 is a classic voltage-feedback amplifier with each channel having two high-impedance inputs and a

low-impedance output. Standard application circuits (as shown in Figure 62 and Figure 63) include the

noninverting and inverting gain configurations. The DC operating point for each configuration is level-shifted by

the reference voltage VREF that is typically set to midsupply in single-supply operation. VREF is often connected to

ground in split-supply applications.
