RECOMMENDED OPERATING CONDITIONS

Parameter
Power Supplies
(Note 6)
Note 1. All voltages with respect to ground
Note 6. The power up sequence between AVDD, DVDD and SVDD is not critical.
When the power supplies are partially powered OFF, the AK4632 must be reset by bringing PDN pin
“
L
”
after
these power supplies are powered ON again.
Note 7. SVDD = 2.6
～
3.6V when 8
dynamic speaker is connected to the AK4632. If SVDD is more than 3.6V when
8
dynamic speaker is connected to the AK4632, the output of Speaker-Amp should be restricted in consideration
of maximum power dissipation as the following.

SPoMax : Maximum Output Power of SPK-Amp[mW]
SPKMPD : Maximum Power Dissipation of SPK-Amp[mW]
Rmin : Minimum Impedance of speaker[
]
Vmax : Maximum permission output voltage of SPK-Amp[Vrms]
SPKMPD = 700 – AVDD(max) x 17.5 – VVDD(max) x 12 – SVDD(max) x 27
A = 2 x sqrt(2) x SVDD(max) /
π
B = A x A – 4 x Rmin x SPKMPD / 1000
Vmax= (A – sqrt(B)) / 2
SPoMax = 1000 x Vmax x Vmax / Rmin
Maximum Output Power of SPK-Amp at B < 0 : No limitation
Maximum Output Power of SPK-Amp at B
≥
0: This power should be less than or equal to
SPoMax[mW].
Regardless of the condition of B, the distortion of output signal increases, when SPK-Amp output power
exceeds 240mW.
Note 8. Minimum value is higher value between 2.8V and AVDD[V].
