AK4636 Datasheet, PDF (76/105 Pages) Asahi Kasei Microsystems – 16-Bit Mono CODEC with ALC & MIC/SPK/Video-AMP

[AK4636]
AOPS: Mono Line Output Power-Save Mode
0: Normal Operation (default)
1: Power-Save Mode
Power-save mode is enable at AOPS bit = “1”. POP noise at power-up/down can be reduced by changing at
PMAO bit = “1”. (Figure 52)
PFSDO: Select of signal from SDTO
0: Output of ADC (1^st - HPF)
1: Output of Programmable Filter/ALC (default)
