<Example>
The clocks can be stopped when only MIN-Amp and Speaker-Amp are operating.
(1)
Power Up MIN-Amp and Speaker-Amp: PMBP = PMSPK bits = “0”
→
“1”
(2)
Disable the path of “DAC
SPK-Amp”: DACS bit = “0”
Enable the path of “MIN
SPK-Amp”: BEEPS bit = “0”
→
“1”
(3)
Exit the power-save-mode of Speaker-Amp: SPPSN bit =
“
0
”
→
“
1
”
“

”
time depends on the time constant of external resistor and capacitor connected to MIN pin. If
Speaker-Amp output is enabled before input of MIN-Amp becomes stable, pop noise may occur.
e.g. R=20k, C=0.1

F: Recommended wait time is more than 5
τ
= 10ms.
(4)
Enter the power-save-mode of Speaker-Amp: SPPSN bit = “1”
→
“0”
(5)
Power Down MIN-Amp and Speaker-Amp: PMBP = PMSPK bits = “1”
→
“0”
(6)
Disable the path of “MIN
SPK-Amp”: BEEPS bit = “1”
→
“0”
