Table 5-1 Pin Functions
PIN TYPE(1) DESCRIPTION
NAME NO.
DGND 1, 5 P Digital ground
DVDD 2 P 3.3-V or 1.8-V digital power supply
VR_DIG 4 P Internally regulated 1.5-V digital supply voltage. This pin must not be used to drive external devices
ADR/ FAULT 3 DI/O Different I2 C device address can be set by selecting different pull up resistor to DVDD, see Table 7-5 for details. After power up, ADR/ FAULT can be redefine as FAULT, go to Page0, Book0, set register 0x61 = 0x0b first, then set register 0x60 = 0x01
LRCLK 6 DI Word select clock for the digital signal that is active on the serial port's input data line. In I2S, LJ and RJ, this corresponds to the left channel and right channel boundary. In TDM mode, this corresponds to the frame sync boundary
SCLK 7 DI Bit clock for the digital signal that is active on the input data line of the serial data port.
SDIN 8 DI Data line to the serial data port
SDOUT 9 DO Serial Audio data output. The source data can be Pre-DSP or Post-DSP data, by setting the register 0x30h.
SDA 10 DI/O I2C serial control data interface input/output
SCL 11 DI I2C serial control clock input
PDN 12 DI Power Down, active-low. PDN place the amplifier in Shutdown, turn off all internal regulators. Low, Power Down Device; High, Enable Device.
AVDD 13 P Internally regulated 5-V analog supply voltage. This pin must not be used to drive external devices
AGND 14 P Analog ground
PVDD 15,16,27,28 P PVDD voltage input
PGND 19,24 P Ground reference for power device circuitry. Connect this pin to system ground.
OUT_A+ 26 O Positive pin for differential speaker amplifier output A+
BST_A+ 25 P Connection point for the OUT_A+ bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_A+
OUT_A- 23 O Negative pin for differential speaker amplifier output A-
BST_A- 22 P Connection point for the OUT_A- bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_A-
BST_B- 21 P Connection point for the OUT_B- bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_B-
OUT_B- 20 O Negative pin for differential speaker amplifier output B
BST_B+ 18 P Connection point for the OUT_B+ bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_B+
