IPGA6-0: Input Analog PGA; 97 levels; Commonly Lch and Rch of IPGA0 and IPGA1.
There is not LINE table in IPGA1
IPGA value is reset at PM1-0 = “00”.
Register Name
Input PGA Control
RESET
The IPGA value should be the same or smaller than REF value before the ALC1 operation including the
FADEIN/FADEOUT operation.
When IPGA gain is changed, IPGA6-0 bits should be written while PM1-0 bits are not “00” and ALC bit is
“0”. (refer to “Operation of IPGA” description)
