KA2209B

The KA2209B is a monolithic integrated audio amplifier in a 8-pin plastic dual in line package.It is designed for portable cassette player and radio.

Features of the KA2209B are:(1)wide operating supply voltage: Vcc is 1.8 V to 9 V; (2)low crossover distortion; (3)low quiescent circuit current; (4)briage/stereo configuration.

The absolute maximum ratings of the KA2209B can be summarized as:(1): operating voltage(Vcc) is 1.8 V min and 9 V max; (2): quiescent circuit current(ICCQ) is 9 mA typ when Vi is 0; (3): channel balance(Ca) is -1 dB min, 0 dB typ and 1 dB max(stereo); (4): total harmonic distortion(THD) is 0.5% typ(stereo, RL is 8 ohms, Po is 0.2 W); (5): ripple rejection ratio(RR) is 24 dB min and 30 dB tyo(stereo,f is 100 HZ, C3 is 100 uF); (6): input resistance(Ri) is 100 Kohms min.
