7.4 Device Functional Mode

7.4.1 Mono Mode (PBTL)

The TPA311xD2-Q1 family can be connected in MONO mode enabling up to 100-W output power. This is done

by:

•

Connecting INPL and INNL directly to ground (without capacitors) to set the device in mono mode during

power up

•

Connecting OUTPR and OUTNR together for the positive speaker terminal and OUTNL and OUTPL together

for the negative terminal

•

Applying the analog input signal to INPR and INNR
