| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| AGND | 8 | — | Analog supply ground, connect to the thermal pad. |
| AVCC | 7 | P | Analog supply |
| AVCC | 14 | P | Connect AVCC supply to this pin |
| BSN | 22, 26 | I | Bootstrap I/O for negative high-side FET |
| BSP | 17, 21 | I | Bootstrap I/O for positive high-side FET |
| FAULT | 2 | O | Open drain output used to display short circuit or DC-detect fault status. Voltage compliant to AVCC. Short circuit faults can be set to auto-recovery by connecting FAULT pin to SD pin. Otherwise both short circuit faults and DC-detect faults must be reset by cycling PVCC. |
| GAIN0 | 5 | I | Gain select least significant bit. TTL logic levels with compliance to AVCC. |
| GAIN1 | 6 | I | Gain select most significant bit. TTL logic levels with compliance to AVCC. |
| GND | 3, 4 | — | Connect to local ground |
| GVDD | 9 | O | High-side FET gate drive supply, nominal voltage is 7 V. This pin can also be used as supply for PLIMIT divider. Add a 1-μF capacitor to ground at this pin. |
| INN | 11 | I | Negative audio input, biased at 3 V. |
| INP | 12 | I | Positive audio input, biased at 3 V. |
| NC | 13 | — | Not connected |
| OUTN | 23, 25 | O | Class-D H-bridge negative output |
| OUTP | 18, 20 | O | Class-D H-bridge positive output |
| PGND | 19, 24 | — | Power ground for the H-bridges |
| PLIMIT | 10 | I | Power limit level adjust. Connect directly to GVDD pin for no power limiting. Add a 1-μF capacitor to ground at this pin. |
| PVCC | 15, 16, 27, 28 | P | Power supply for H-bridge. PVCC pins are also connected internally. |
| SD | 1 | I | Shutdown logic input for audio amplifier (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with compliance to AVCC. |
