Typical Operating Characteristics (continued)
(AVDD = CPVDD = +3V, DVDD = DVDDS2 = +1.8V, PVDD = +3.3V, RHP = 32
Ω, ZSPK = 8Ω + 10H, RREC = 32Ω, ROUTL+ to ROUTL- =
ROUTR+ to ROUTR- = 10k
Ω, C1 = 0.22F, C2 = CVMREG = CVPREG = CMBIAS = CREF = 1F, MCLK = 13MHz, all PGAs = 0dB,
HP/REC volume = -20.0dB, SPK volume = -20.4dB, line output gain = -0.4dB, fS = 48kHz for nonvoice mode, TA = TMIN to TMAX,
unless otherwise noted. Typical values are at TA = +25°C.)
