ELECTRICAL CHARACTERISTICS (continued)
(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.)
