Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.

Electrical Characteristics

(VAVDD = VPVDD = 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 HPGND. Line out loads (RLOAD) connected from LOUTL and LOUTR to ground. RLOAD = RHP = J, RREC = J, ZSPK

= J, CREF = 2.2FF, CMICBIAS = CREG = 1FF, CC1N-C1P = 1FF, CHPVDD = CHPVSS = 1FF. AVMICPRE_ = +20dB, AVMICPGA_ = 0dB,

AVDACATTN = 0dB, AVDACGAIN = 0dB, AVADCLVL = 0dB, AVADCGAIN = 0dB, AVPGAIN_ = 0dB, AVHP_ = 0dB, AVREC = 0dB, AVSPK_

= 0dB, MCLK = 12.288MHz, LRCLK = 48kHz, MAS = 1. TA = +25NC, unless otherwise noted.) (Note 1)
