Pin Configuration
| Pin | Name | Type | Description |
|---|---|---|---|
| 1 | DIN | - | Digital Input Signal |
| 2 | GAIN_SLOT | - | Gain and Channel Selection. In I2S and LJ mode determines amplifier output gain (Table 8). In TDM mode, used for channel selection with SD_MODE (Table 7). In TDM mode, gain is fixed at 12dB. |
| 4 | SD_MODE | - | Shutdown and Channel Select. Pull SD_MODE low to place the device in shutdown. In I2S or LJ mode, SD_MODE selects the data channel (Table 5). In TDM mode, SD_MODE and GAIN_SLOT are both used for channel selection (Table 7). |
| 9 | OUTP | - | Positive Speaker Amplifier Output |
| 10 | OUTN | - | Negative Speaker Amplifier Output |
| 14 | LRCLK | - | Frame Clock. Left/right clock for I2S and LJ mode. Sync clock for TDM mode. |
| 16 | BCLK | - | Bit Clock Input |
| 3, 11, 15 | GND | - | Ground |
| 5, 6, 12, 13 | N.C. | - | No Connection |
| 7, 8 | VDD | - | Power-Supply Input |
| EP | EP | - | Exposed Pad. The exposed pad is not internally connected. Connect the exposed page to a solid ground plane for thermal dissipation. |
