NAME NO.
BST_A 59 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 55 P High-side bootstrap supply for half-bridge D
BYPASS 56 O Nominally equal to V
CC
/8. Internal reference voltage for analog cells
DVDD 15, P 3.3-V digital power supply
33
DVSS 20, P Digital ground
26
HPL_PWM 37 DO Headphone left-channel PWM output
HPR_PWM 38 DO Headphone right-channel PWM output
HPSEL 30 DI 5-V Headphone select, active high. When a logic HIGH is applied, device
enters headphone mode and speakers are hard-muted. When a 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 34 DI 5-V MCLK is the clock master input. The input frequency of this clock can
range from 2.822 MHz to 49 MHz.
MUTE 21 DI 5-V Pullup 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
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
OUT_C 49, O Output, half-bridge C
50
OUT_D 45, O Output, half-bridge D
46
PDN 17 DI 5-V Pullup Power down, active-low. PDN powers down all logic, stops all clocks,
and outputs stops switching. When PDN is released, the device
powers up all logic, starts all clocks, and performs a soft start that
returns to the previous configuration determined by register settings.
PGND_A 6, 7 P Power ground for half-bridge A
PGND_B 2, 3 P Power ground for half-bridge B
PGND_C 47, P Power ground for half-bridge C
48
PGND_D 43, P Power ground for half-bridge D
44
PLL_FLTM 12 AO PLL negative input
PLL_FLTP 13 AI PLL positive input
PVCC_A 8, 9 P Power supply input for half-bridge output A
PVCC_B 62, P Power supply input for half-bridge output B
63
PVCC_C 51, P Power supply input for half-bridge output C
52
PVCC_D 41, P Power supply input for half-bridge output D
