ELECTRICAL CHARACTERISTICS (VDD = 3.3V) (continued)
(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)
