3.5 IOVDD Power Supply Options

IOVDD supply to TAS2320 is powered by AC-MB through IOVDD_MB selection. For simplicity, the same IOVDD voltage selected on AC-MB is used for TAS2320.

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, an external IOVDD must be connected to the IOVDD test point close to TAS2320 - U1.
