ELECTRICAL CHARACTERISTICS (continued)
(PVDD = VDD = +18V, PGND = GND = 0V, CSS = 0.47F, CREG = 0.01F, C1 = 0.1F, C2 = 1F, RLOAD = ∞, MONO = low (stereo
mode), SHDN = MUTE = high, G1 = low, G2 = high (AV = 22dB), FS1 = FS2 = high (SSM), SYNCIN = low. All load resistors (RL) are
connected between OUT_+ and OUT_-, unless otherwise stated. TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA
= +25°C.) (Note 1)
