2 x 1.5W, Stereo Class D Audio Subsystem
with DirectDrive Headphone Amplifier
Typical Operating Characteristics
(VDD = PVDD = CPVDD = 3.3V, GND = PGND = CPGND = 0V, SHDN = VDD, I2C default gain settings (INA gain = +20dB, INB gain =
INC gain = 0dB, volume setting = 0dB, mono path gain = 0dB, SHDN = 1, SSM = 1). Speaker load resistors (RLSP) are terminated
between OUT_+ and OUT_-, headphone load resistors are terminated to GND, unless otherwise stated. C1 = C2 = C3 = 1µF. TA =
+25°C, unless otherwise noted.)
