Table 1. Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
AM[2:0] 13–15 I AM avoidance frequency selection
AVCC 17 P Analog supply
BSNL 20 BST Bootstrap for negative left channel output, connect to 220-nF X5R, or better ceramic cap to OUTPL
BSNR 26 BST Bootstrap for negative right channel output, connect to 220-nF X5R, or better ceramic cap to OUTNR
BSPL 24 BST Bootstrap for positive left channel output, connect to 220-nF X5R, or better ceramic cap to OUTNL
BSPR 30 BST Bootstrap for positive right channel output, connect to 220-nF X5R or better ceramic cap to OUTPR
FAULT 3 DO General fault reporting including overtemperature, dc detect, open drain.
FAULT = High, normal operation
FAULT = Low, fault condition
GAIN/SLV 8 I Selects gain and selects between master and slave modes depending on pin voltage divider.
GND 9, 22, 25, 28 G Ground
GVDD 7 PO Internally generated gate voltage supply. Not to be used as a supply or connected to any component other than a 1-µF X7R ceramic decoupling capacitor and the PLIMIT and GAIN/SLV resistor dividers.
LINN 11 I Negative audio input for left channel. Biased at 3 V. Connect to GND for PBTL mode.
LINP 10 I Positive audio input for left channel. Biased at 3 V. Connect to GND for PBTL mode.
MODSEL 1 I Mode selection logic input (LOW = BD mode, HIGH = 1 SPW mode). TTL logic levels with compliance to AVCC.
MUTE 12 I Mute signal for fast disable or enable of outputs (HIGH = outputs Hi-Z, LOW = outputs enabled). TTL logic levels with compliance to AVCC.
OUTNL 21 PO Negative left-channel output
OUTNR 27 PO Negative right-channel output
OUTPL 23 PO Positive left-channel output
OUTPR 29 PO Positive right-channel output
PLIMIT 6 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.
PVCC 18, 19, 31, 32 P Power supply
RINN 5 I Negative audio input for right channel. Biased at 3 V.
RINP 4 I Positive audio input for right channel. Biased at 3 V.
SD 2 I Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with compliance to AVCC.
SYNC 16 DIO Clock input/output for synchronizing multiple class-D devices. Direction determined by GAIN/SLV pin.
Thermal pad — G Connect to GND for best system performance. If not connected to GND, leave floating.
(1) TYPE: DO = Digital output, I = Analog input, G = General ground, PO = Power output, BST = Bootstrap.
