Pin Functions

PIN INPUT/ OUTPUT/ POWER (I/O/P) DESCRIPTION
NAME WCSP
PVDD A1 O Boost converter output and Class-D power stage supply voltage.
SW A2 I Boost converter switch input; connect boost inductor between VBAT and SW.
BGND A3 P Boost converter power ground.
OUT+ B1 O Positive audio output.
AGC B2 I AGC inflection point select. Connect to VDD, GND or Float. Voltage at AGC pin is only read at device power-up. A power cycle is required to change inflection points.
VBAT B3 P Supply voltage.
OUT– C1 O Negative audio output.
EN C2 I Device enable; set to logic high to enable.
IN+ C3 I Positive audio input.
PGND D1 P Class-D power ground.
AGND D2 P Analog ground.
IN– D3 I Negative audio input.
