Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
ADR/FAULT 8 DIO Dual function terminal which sets the LSB of the 7-bit I2C address to "0" if pulled to GND and to "1" if pulled to DVDD. If configured to be a fault output by the methods described in I²C Address Selection and Fault Output, this terminal is pulled low when an internal fault occurs. A pull-up or pull-down resistor is required, as is shown in the Typical Application Circuit Diagrams. If pulled high (to DVDD), a 15-kΩ resistor must be used to minimize in-rush current at power up and to isolate the net if the pin is used as a fault output, as described above.
AVDD 9 P 3.3-V analog power supply
AVSS 13,14 P Analog 3.3-V supply ground
BST_A 17 P High-side bootstrap supply for half-bridge A
BST_B 28 P High-side bootstrap supply for half-bridge B
BST_C 29 P High-side bootstrap supply for half-bridge C
BST_D 40 P High-side bootstrap supply for half-bridge D
DVDD 47 P 3.3-V digital power supply
DVSS 44,46 P Digital ground
DVSS_OSC 3 P Oscillator ground
GVDD 41 P Gate drive internal regulator output
LRCLK 56 P Input serial audio data left/right clock (sample-rate clock)
MCLK 5 DI Master clock input
NC 6,7,22,35,43,45,50,51 – No connect
OSC_RES 4 AO Oscillator trim resistor. Connect an 18.2-kΩ, 1% resistor to DVSS_OSC ground.
OUT_A 20,21 O Output, half-bridge A
OUT_B 26,27 O Output, half-bridge B
OUT_C 30,31 O Output, half-bridge C
OUT_D 36,37 O Output, half-bridge D
PBTL 15 DI Low means BTL mode; high means PBTL mode. Information goes directly to power stage.
PDN 1 DI Power down, active-low. PDN prepares the device for loss of power supplies by shutting down the noise shaper and initiating the PWM stop sequence.
PGND 23,24,25, 32,33,34 P Power ground for half-bridges A and B
FLTM 12 AO PLL negative loop-filter terminal
FLTP 11 AO PLL positive loop-filter terminal
PVDD_AB 18,19 P Power-supply input for half-bridge output A and B
PVDD_CD 38,39 P Power-supply input for half-bridge output C and D
RESET 49 DI Reset, active-low. A system reset is generated by applying a logic low to this pin. RESET is an asynchronous control signal that restores the DAP to its default conditions and places the PWM in the hard-mute (high-impedance) state.
SCL 52 DI I2C serial control clock input
SCLK 55 DI Serial audio-data clock (shift clock). SCLK is the serial-audio-port input-data bit clock.
SDA 53 DIO I2C serial control data interface input/output
SDIN 54 DI Serial audio data input. SDIN supports three discrete (stereo) data formats.
SSTIMER 16 AI Controls ramp time of OUT_x to minimize pop. Leave this pin floating for BD mode. Requires capacitor of 2.2 nF to GND in AD mode. The capacitor determines the ramp time.
STEST 48 DI Factory test pin. Connect directly to DVSS.
VR_ANA 10 P Internally regulated 1.8-V analog supply voltage. This pin must not be used to power external devices.
VR_DIG 2 P Internally regulated 1.8-V digital supply voltage. This pin must not be used to power external devices.
VREG 42 P Digital regulator output. Not to be used for powering external circuitry.
PowerPAD™ P Connect to GND for best system performance. If not connected to GND, leave floating.
(1) TYPE: A = analog; D = 3.3-V digital; P = power/ground/decoupling; I = input; O = output
