The single ended output can drive headphone loads of 16Ω or 32Ω or a line output. The MOUT can be manipulated
by changing attenuation and the volume (loudness of the output signal).
The output stage is powered by the speaker supply, VDDSPK, which are capable of driving up to 1.5V
The MONO output can be enabled for signal output or muted. The output pins are at reference DC level when the
output is muted.
