Table 1. Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 SD I Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with compliance to AVCC.
2 FAULT 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.
3 LINP I Positive audio input for left channel. Biased at 3 V.
4 LINN I Negative audio input for left channel. Biased at 3 V.
5 GAIN0 I Gain select least significant bit. TTL logic levels with compliance to AVCC.
6 GAIN1 I Gain select most significant bit. TTL logic levels with compliance to AVCC.
7 AVCC P Analog supply
8 AGND — Analog signal ground. Connect to the thermal pad.
9 GVDD O High-side FET gate drive supply. Nominal voltage is 7V. Also should be used as supply for PLIMIT function.
10 PLIMIT I Power limit level adjust. Connect a resistor divider from GVDD to GND to set power limit. Connect directly to GVDD for no power limit.
11 RINN I Negative audio input for right channel. Biased at 3 V.
12 RINP I Positive audio input for right channel. Biased at 3 V.
13 NC — Not connected
14 PBTL I Parallel BTL mode switch
15 PVCCR P Power supply for right channel H-bridge. Right channel and left channel power supply inputs are connect internally.
16 PVCCR P Power supply for right channel H-bridge. Right channel and left channel power supply inputs are connect internally.
17 BSPR I Bootstrap I/O for right channel, positive high-side FET.
18 OUTPR O Class-D H-bridge positive output for right channel.
19 PGND — Power ground for the H-bridges.
20 OUTNR O Class-D H-bridge negative output for right channel.
21 BSNR I Bootstrap I/O for right channel, negative high-side FET.
22 BSNL I Bootstrap I/O for left channel, negative high-side FET.
23 OUTNL O Class-D H-bridge negative output for left channel.
24 PGND — Power ground for the H-bridges.
25 OUTPL O Class-D H-bridge positive output for left channel.
26 BSPL I Bootstrap I/O for left channel, positive high-side FET.
27 PVCCL P Power supply for left channel H-bridge. Right channel and left channel power supply inputs are connect internally.
28 PVCCL P Power supply for left channel H-bridge. Right channel and left channel power supply inputs are connect internally.
