Dual function terminal which sets the LSB of the 7-bit I²C address to 0 if pulled to GND, 1 if pulled to DVDD. If configured to be a fault output via the System Control ADR/SPK_FAULT 20 DI/DO - Register 2 (0x05), this terminal is pulled low when an internal fault with the speaker amplifier occurs. A pull-up or pull-down resistor is required, as is shown in the Typical Application Circuit Diagrams. AGND 36 P - Ground for analog circuitry(2) AVDD 19 P - Power supply for internal analog circuitry Linear voltage regulator output derived from AVDD supply which is used for internal ANA_REG1 18 P - analog circuitry. Nominal 1.8 V output.(3) Linear voltage regulator output derived from AVDD supply which is used for internal ANA_REG2 37 P - analog circuitry. Nominal 3.3 V output.(3) Connection points for the bootstrap capacitors, which are used to create a power BSTRPx 3, 42, 46, 47 P - supply for the high-side gate drive of the device DGND 35 P - Ground for digital circuitry(2) Linear voltage regulator output derived from DVDD supply which is used for internal DIG_REG 24 P - digital circuitry(3) Negative terminal for capacitor connection used in headphone amplifier and line DR_CN 12 P - driver charge pump Positive terminal for capacitor connection used in headphone amplifier and line DR_CP 13 P - driver charge pump DR_INx 7, 10 AI - Input for channel A or B of headphone amplifier or line driver DR_OUTx 8, 9 AO - Output for channel A or B of headphone amplifier or line driver DR_SDI 39 DI - Places the headphone amplifier/line driver in shutdown when pulled low. Negative supply generated by charge pump for ground centered headphone and DRVSS 11 P - line driver output DRVDD 14 P - Power supply for internal headphone and line driver circuitry (1) TYPE: AI = Analog input, AO = Analog output, DI = Digital Input, DO = Digital Output, P = Power, G = Ground (0V) (2) This terminal should be connected to the system ground (3) This terminal is provided as a connection point for filtering capacitors for this supply and must not be used to power any external circuitry.
