Mono 1.4W Class AB Audio Amplifiers
ELECTRICALCHARACTERISTICS(continued)
(VDD = 3.7V, VGND = 0V, SHDN = VDD, GAIN = VDD (0dB), CBIAS = 0.1F, CIN = 0.47F, no load: RIN = RF = 10kI (MAX98309),
TA = TMIN to TMAX. Typical values are at TA = +25°C, unless otherwise noted.) (Note 2)
Note2: All specifications are 100% tested at TA = +25°C; temperature limits are guaranteed by design.
Note3: Inputs AC-coupled to GND.
Note4: Mode transitions controlled by SHDN.
Note5: Thermally limited by package.
