STEREO: Mono/Stereo Mode Select
“0”: Mono
“1”: Stereo
SIGNED: Unsigned/Signed Mode Select
“0”: Unsigned (“0” is valid only when the resolution is 8 bit)
“1”: Signed
RES1-0: ADC Resolution Mode Select
“00”: 8bit
“01”: 16bit
“10”: 24bit
MIX: ADC Data Mix Control
“0”: Lch and Rch are not mixed.
“1”: Lch and Rch are mixed. Dynamic range and S/N can be improved by approximately 3dB when the same analog
signal is inputted to left and right channels.
