Note 1)
Typical values are typical under the recommended operating conditions. Maximum values are the
maximum conditions under the recommended operating conditions.The high levels of inputs
are defined as that of VDD1, and the low levels as that of VSS
Note 2)
Total current of VDD1, AVDDR, AHVDD, and AHVDDG
Note 3)
Total current of VDD2 and DVDD
Note 4)
Typical value is at Dolby Digital. Maximum values are at PCM 2-chanel 192kHz+Dolby Pro Logic
IIx+Bass Management.
Note 5)
Value in power-down mode 3. XI input is at high level.
Note 6)
The current consumption increases during power-down at higher temperatures.
