Typical Operating Characteristics (continued)
(VLDOIN = VPVDD = 3.7V, VGND = VPGND = 0V. Single-ended inputs, preamp gain = 0dB, HPLVOL = HPRVOL = SPKVOL = 0dB. Speaker
loads (ZSPK) connected between OUTP and OUTN. Headphone loads (RHP) connected from HPL or HPR to GND. ZSPK = ∞, RHP = ∞.
CC1P-C1N = CHPVDD = CHPVSS = CBIAS = 1μF. TA = +25°C, unless otherwise noted.)
