PRODUCTION DATA.
| PIN | TYPE(1) | TERMINATION | DESCRIPTION | |
|---|---|---|---|---|
| NAME | NUMBER | |||
| ADR/SPK_FAULT | 20 | DI/DO | — | Dual-function pin 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 Register 2 (0x05), this pin is pulled low when an internal fault with the speaker amplifier occurs. A pullup or pulldown resistor is required, as is shown in the Typical Applications. |
| AGND | 36 | P | — | Ground for analog circuitry(3) |
| AVDD | 19 | P | — | Power supply for internal analog circuitry |
| ANA_REG1 | 18 | P | — | Linear voltage regulator output derived from AVDD supply which is used for internal analog circuitry. Nominal 1.8-V output.(2) |
| ANA_REG2 | 37 | P | — | Linear voltage regulator output derived from AVDD supply which is used for internal analog circuitry. Nominal 3.3-V output.(2) |
| BSTRPx | 3, 42, 46, 47 | P | — | Connection points for the bootstrap capacitors which are used to create a power supply for the high-side gate drive of the device. |
| DGND | 35 | P | — | Ground for digital circuitry(3) |

| MCLK | 21 | DI | Pulldown | Master clock used for internal clock tree and sub-circuit and state machine clocking |
| NC | 31 | — | — | Not connected inside the device (all NC terminals should be connected to ground for optimal thermal performance) |
| OSC_GND | 23 | P | — | Ground for oscillator circuitry (this terminal should be connected to the system ground) |
| OSC_RES | 22 | AO | — | Connection point for oscillator trim resistor |
| PDN | 25 | DI | Pullup | Quick powerdown of the device that is used upon an unexpected loss of the PVDD or DVDD power supply to quickly transition the outputs of the speaker amplifier to Hi-Z. This quick powerdown feature avoids the audible anamolies that would occur as a result of loss of either of the supplies. |

| PLL_GND | 15 | P | — | Ground for PLL circuitry (this terminal should be connected to the system ground) |
| PowerPAD™ | — | P | — | Thermal and ground pad that provides both an electrical connection to the ground plane and a thermal path to the PCB for heat dissipation. This pad must be grounded to the system ground. (3) |
| PVDD | 4, 41 | P | — | Power supply for internal power circuitry |
