TERMINAL FUNCTIONS

TERMINAL

I/O DESCRIPTION

NAME NO.

Active low. Shutdown signal for IC (LOW = disabled, HIGH = operational). TTL logic levels with

SHUTDOWN 29 I

compliance to AVCC.

INP 1 I Positive audio input

INN 2 I Negative audio input

GAIN0 5 I Gain select least significant bit. TTL logic levels with compliance to VREG.

GAIN1 6 I Gain select most significant bit. TTL logic levels with compliance to VREG.

Active high. Mute signal for quick disable/enable of outputs (HIGH = outputs high-Z, LOW = outputs

MUTE 30 I

enabled). TTL logic levels with compliance to AVCC.

TTL compatible output. HIGH = short-circuit fault. LOW = no fault. Only reports short-circuit faults.

FAULT 31 O

Thermal faults are not reported on this terminal.

BSP 23 I/O Bootstrap I/O for left channel, positive high-side FET.

14, 15,

PVCC Power supply for left channel H-bridge, not internally connected to AVCC.

26–28

OUTP 21, 22 O Class-D 1/2-H-bridge positive output

16, 17,

PGND Power ground for H-bridge.

24, 25

OUTN 19, 20 O Class-D 1/2-H-bridge negative output

BSN 18 I/O Bootstrap I/O for left channel, negative high-side FET.

VCLAMP 13 Internally generated voltage supply forbootstrap capacitor.

AGND 3, 4, 12 Analog ground for digital/analog cells in core.

ROSC 9 I/O I/O for current setting resistor of ramp generator.
