Analog Mixing: Full-differential Mono Input (L4DIF bit = “1”: IN4+/IN4
pins)
When L4DIF bit = “1”, LIN4 and RIN4 pins becomes IN4+ and IN4
pins, respectively.
When PMAINL4 bit = “1”, IN4+ and IN4
pins can be used as full-differential mono line input for analog mixing. When
the LINH4 and RINH4 bits are set to “1”, the input signal from the IN4+/IN4
pins is output to Headphone-Amp. When
the LINL4/RINR4 bits are set to “1”, the input signal from the IN4+/IN4
pins is output to the stereo line output
amplifier.
Table 44
,
Table 45
and
Table 46
show the typical gain. Input signal amplitude is defined as (IN4+)
(IN4
).
