ELECTRICAL CHARACTERISTICS (VDD = 5.0V) (continued)
(VDD = PVDD = SHDN = MUTE = 5V, GND = PGND = 0V, SYNC = 0V (FFM). Gain = 12dB (G1 = 0, G2 = 1). Speaker load resistor
(RL) connected between OUT+ and OUT-, unless otherwise noted, RL =
∞, TA = TMIN to TMAX, unless otherwise noted. Typical val-
ues are at TA = +25°C.) (Notes 1, 2)
