ELECTRICAL CHARACTERISTICS
(VDD = VPVDDL = VPVDDR = 3.7V, VCCIO = 1.8V, VGND = VPGNDL = VPGNDR = 0. Single-ended inputs, preamp = 0, volume controls =
0dB, BYPASS = 0, SHDN = 1. Speaker loads connected between OUT_+ and OUT_-. Headphone loads connected from HPL or HPR to
GND. RSPK = ∞, RHP = ∞. C1 = C2 = CBIAS = 1F. TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
(Notes 3, 4)
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.
Note 1: HPR and HPL should be limited to no more than 9V above VSS, or above PVDD + 0.3V, whichever limits first.
Note 2: HPR and HPL should be limited to no more than 9V below PVDD, or below VSS - 0.3V, whichever limits first.
