dear Ti support engr,
i want to know from the basic apps diagram for driving a single speaker in BTL mode if the inputs must be driven in opposite phase...

Hung Huynh Trung, there are 2 ways to drive a mono load with TAS5613A. (TAS5613 is not recommended for new designs.)
- BTL: see page 16 of data sheet SLAS711 (copy attached). This schematic shows differential inputs (driven in opposite phase), and these are preferrable for noise rejection.
- PBTL: see page 17 of the data sheet.

Steve.
dear steve,
thanks for that answer in case of mono btl is that true that this circuit can output more than 120 W rms at 4 ohms with less than 1%thd in a single sub-woofer...regards

Hung Huynh Trung, with a single BTL output 125W into 4ohms at 1% THD+N is typical for our devices with test conditions shown on page 8 of the data sheet. The PBTL typical output is 130W, and that provides extra margin.
