Typical Operating Characteristics (continued)
(VDD = VPVDDL = VPVDDR = 3.7V, VCCIO = 1.8V, VGND = VPGNDL = VPGNDR = 0. Single-ended inputs, preamp = 0dB, volume con-
trols = 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 = +25°C, unless otherwise noted.)
