P
High-side bootstrap supply for half-bridge A
BST_B
61
P
High-side bootstrap supply for half-bridge B
BST_C
53
P
High-side bootstrap supply for half-bridge C
BST_D

O
Nominally equal to VCC/8. Internal reference voltage for analog cells
15,
DVDD
P
3.3-V digital power supply
33
20,
DVSS
P
Digital ground
26
HPL_PWM
37
DO
Headphone left-channel PWM output.
HPR_PWM
38
DO
Headphone right-channel PWM output.
Headphone select, active high. When a logic HIGH is applied, device
enters headphone mode and speakers are HARD MUTED. When a
HPSEL
30
DI
5-V
logic LOW is applied, device is in speaker mode and headphone
outputs become line outputs or are disabled.
LRCLK
22
DI
5-V
Input serial audio data left/right clock (sampling rate clock)
MCLK is the clock master input. The input frequency of this clock can
MCLK
34
DI
5-V
range from 4.9 MHz to 49 MHz.
Performs a soft mute of outputs, active-low. A logic low on this
terminal sets the outputs equal to 50% duty cycle. A logic high on this
MUTE
21
DI
5-V
Pullup
terminal allows normal operation. The mute control provides a
noiseless volume ramp to silence. Releasing mute provides a
noiseless ramp to previous volume.
OSC_RES
19
AO
Oscillator trim resistor. Connect an 18.2-k
resistor to GND.
OUT_A
4, 5
O
Output, half-bridge A
OUT_B
1, 64
O
Output, half-bridge B
49,
OUT_C
O
Output, half-bridge C

OUT_D
O
Output, half-bridge D
46
Power down, active-low. PDN powers down all logic, stops all clocks,
and outputs stops switching. When PDN is released, the device
PDN
17
DI
5-V
Pullup
powers up all logic, starts all clocks, and performs a soft start that
returns to the previous configuration determined by register settings.
