Hi.
TPA6211A1 is connected to the output of PCM2912A.
It is connected to a mono speaker after amplifying the audio with TPA6211A1.
How should I handle the pins of unused channels when operating the PCM2912A in monaural?
Hello,
The unused analog output pins can be left floating, or terminated to GND with a higher value resistor of choice depending on acceptable power levels.
