ELECTRICAL CHARACTERISTICS (continued)
(VVDD = 1.8V, VPVDD = 3.7V, VGND = 0V. Input signal applied at INA configured single-ended, 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. SDA and SCL pullup voltage = 1.8V. ZSPK = J, RHP = J. CC1P-C1N = CHPVDD = CHPVSS = CBIAS = 1FF.
TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25NC.) (Note 1)
