3.4 IOVDD Power Supply Options

IOVDD supply to TAS2118 is powered by AC-MB. For simplicity, the same IOVDD voltage selected on AC-MB is used for TAS2118.

J3 on the bottom side of the EVM can be used to open this power supply connection for current measurement purposes. If J3 is open, then an external IOVDD must be connected to the IOVDD test point close to TAS2118 - U1.
