ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS (VDD = 3.3V)
(VDD = PVDD = CPVDD = SHDN = 3.3V, GND = PGND = CPGND = 0V, SYNC = VDD (SSM), speaker gain = +12dB, headphone gain
= +1dB. Speaker load RL connected between OUT+ and OUT-, unless otherwise noted, RL =
∞. Headphone load RLH connected
between HPR/HPL to GND. CBIAS = 1F to GND, 1F capacitor between C1P and C1N, CVSS = 1F. TA = TMIN to TMAX, unless oth-
erwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
