4.1 Use With a Dual SOIC Amplifier in a Composite Loop

The BUF634ADRBEVM and BUF634ADDAEVM feature the option to configure the BUF634A devices in two composite amplifier loops using a dual SOIC package amplifier, such as the OPA2810. The BUF634A forms an output driving stage for the chosen input amplifier in the composite loop and forms a differential composite amplifier useful for applications (such as audio amplification) with the dual paths on the EVM. Populate the device U1; resistors R2, R3, R4, and R5; capacitors C2 and C4; and remove resistors R11 and R16 when configuring the EVM to use the composite loop.
