High-Efficiency, Low-Noise Audio Subsystem
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 1.8V, VPVDD = 4.2V, VGND = VPGND = 0V. Headphone path: PGAIN_ = -1.5dB, HP_VOL = 0dB, HPGAIN = +2dB, input signal
configured single-ended. Speaker path: PGAIN_ = 0dB, SPKVOL = 0dB, SPKGAIN = +12dB, input signal configured differential.
Speaker loads (ZSPK) connected between SPKP and SPKN. Headphone loads (RHP) connected from HPL or HPR to GND. SDA and
SCL pullup voltage = 1.8V. ZSPK = J, RHP = J. CC1P-C1N = CCPVDD = CCPVSS = CBIAS = 1FF. TA = TMIN to TMAX, unless otherwise
noted. Typical values are at TA = +25NC.) (Note 1)
