Figure 28. Mono Line Output
When DAMO bit is “1”, mono mixer mixes Lch and Rch signal from DAC. This mixed signal is output to mono line
output that is differential output. When MICM bit is “1”, Lch signal from IPGA is output to mono line output. Either
MOUT+ or MOUT
pin can be used as single-ended output pin. The load impedance is 20k
(min.). When the PMMO
bit is “0”, the mono line output enters power-down-mode and the output is placed in a Hi-Z state.
ATTL7-0 and ATTR7-0 bits set the volume control of DAC output. ATTM bit sets the volume control of IPGA Lch
output. Amp for mono line output has 6dB gain and
17dB gain that are set by the MOGN bit.
