Electrical Characteristics (Continued)
Unless otherwise noted: HPA uses stereo single-ended inputs, SPA uses differential input, unused inputs AC are
grounded, fIN = 1KHz, AGC off, PGAINxx = 0dB, HPxVOL = 0dB, PRESENTGAIN = 6dB, ERC = 1, SSMT = 000,
SHDNB = 1, SDB = 1.8V, SDA and SCL pull-up voltage = 1.8V, ZSPK = 8+68H, RHP = 32, speaker amplifier and
headphone amplifier on. Typical values are at VBATT = 3.7V, TA = 25°C. Minimum and maximum values are at VBATT =
2.80V to 5.25V, TA = -40°C to 85°C.
