2.4W, Single-Supply, Class G Power Amplifier
Typical Operating Characteristics
(VCC = CPVDD = SHDN = 3.6V, GND = CPGND = 0V, RIN+ = RIN- = 10kΩ, RFB+ = RFB- = 10kΩ, RFS = 100kΩ, C1 = 4.7µF, C2 =
10µF, RL = 8Ω; speaker load resistors (RL) are terminated between OUT+ and OUT-, unless otherwise stated; TA = TMIN to TMAX,
unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)
