7.4 Device Functional Modes

7.4.1 Mono Mode (PBTL)

The TPA31xxD2 family can be connected in MONO mode enabling up to 100W output power. This is done by:
•

Connect INPL and INNL directly to Ground (without capacitors) this sets the device in Mono mode during
power up.

•

Connect OUTPR and OUTNR together for the positive speaker terminal and OUTNL and OUTPL together for
the negative pin.

•

Analog input signal is applied to INPR and INNR.
