LOUT2/ROUT2 OUTPUTS
The LOUT2 and ROUT2 output pins are essentially similar to LOUT1 and ROUT1, but they are
independently controlled and can also drive an 8
Ω mono speaker (see Speaker Output section). For
speaker drive, the ROUT2 signal must be inverted (ROUT2INV = 1), so that the left and right channel
are mixed to mono in the speaker [L–(-R) = L+R].

MONO OUTPUT
The MONOOUT pin can drive a mono line output. The signal volume on MONOOUT can be adjusted
under software control by writing to MONOOUTVOL.
