Output Sequence
<Example>
The clock is not needed to supply when only BEEP-Amp and Speaker-Amp are operating.
(1) Power Up BEEP-Amp and Speaker-Amp: PMBP bit = PMSPK bit =
“
0
”
→
“
1
”
(2) Enable the path of
“
BEEP
SPK-Amp
”
: BEEPS bit =
“
0
”
→
“
1
”
(3) Exit the power-save-mode of Speaker-Amp: SPPSN bit =
“
0
”
→
“
1
”
“
(4)
”
time depends on the time constant of external resistor and capacitor connected to BEEP pin. If
Speaker-Amp output is enabled before input of BEEP-Amp becomes stable, pop noise may occur.
e.g. R=20k, C=0.1
μ
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 BEEP-Amp and Speaker-Amp: PMBP bit = PMSPK bit =
“
1
”
→
“
0
”
(6) Disable the path of
“
BEEP
SPK-Amp
”
: BEEPS bit =
“
1
”
→
“
0
”
