ELECTRICAL CHARACTERISTICS (continued)
(VAVDD = VHPVDD = VDVDD = VDVDDS1 = VDVDDS2 = +1.8V, VSPKLVDD = VSPKRVDD = 3.7V. Speaker loads (ZSPK) connected
between SPK_P and SPK_N. Receiver load (RREC) connected between RECP and RECN. Headphone loads (RHP) connected from
HPL or HPR to GND. RHP = J, RREC = J, ZSPK = J, CREF = 2.2FF, CMICBIAS = CPREG = CREG = 1FF, CC1N-C1P = 1FF, CHPVSS
= 1FF. AVMICPRE_ = +20dB, AVMICPGA_ = 0dB, AVDACATTN = 0dB, AVDACGAIN = 0dB, AVADCLVL = 0dB, AVADCGAIN = 0dB,
AVPGAIN_ = 0dB, AVPGAOUT_ = 0dB, AVHP_ = 0dB, AVREC = 0dB, AVSPK_ = 0dB, MCLK = 12.288MHz, LRCLK = 48kHz, MAS = 1.
TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25NC.) (Note 1)
