8 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.

8.1 Application Information

Figure 27 shows the OPA551 connected as a basic noninverting amplifier. The OPA551 can be used in virtually

any operational amplifier configuration. The OPA552 is designed for use in configurations with gains of 5 or

greater. Power-supply terminals must be bypassed with 0.1-µF capacitors, or greater, near the power-supply

pins. Be sure that the capacitors are appropriately rated for the power-supply voltage used. The OPA55x can

supply output currents up to 200 mA with excellent performance.
