Typical Operating Characteristics (continued)
(VDD = PVDD = CPVDD = 3.3V, GND = PGND = CPGND = 0V, SHDN = VDD, I2C settings (INA gain = +20dB, INB gain = INC gain =
0dB, volume setting = 0dB, mono path gain = 0dB, SHDN = 1, SSM = 1). C1 = C2 = C3 = 1F. Speaker load resistors (RLSP) are ter-
minated between OUT+ and OUT-, headphone load resistors are terminated to GND, unless otherwise noted.)
