KIA6240K

The KIA6240K is a kind of dual audio power amplifier for consumer application. It is suitable for power amplifier of TV and home stereo. There are some features as follows: (1)high output power: POUT=6 W (typ) (VCC=22 V, RL=8, f=1 kHz, THD=0.5%); (2)high current capability; (3)AC short circuit protection; (4)thermal overload protection; (5)operation supply voltage range: VCC(opr)=8 to 25 V.

The following is about the maximum ratings of KIA6240K: (1)supply voltage, VCC: 28 V; (2)output current (repetitive f20 Hz), IO(peak): 3 A; (3)output current (non repetitive t=100S), IO(peak): 3.5 A; (4)power dissipation (Tcase=70), PD: 10 W; (5)operating temperature, Topr: -20 to 75; (6)storage temperature, Topr: -55 to 150.

The last one is about the electrical characteristics of KIA6240K(unless otherwise specified, VCC=18 V, f=1 kHz, Ta=25, RL=8, Rg=600): (1)quiescent current, ICCQ: 50 mA typ and 90 mA max at VIN=0; (2)quiescent output voltage, VO: 8.5 V typ; (3)input saturation voltage, VIN: 300 mVrms min; (4)input resistance, RIN: 70 k min and 200 k typ; (5)voltage gain, Gv: 35.5 dB min, 36 dB typ and 36.5 dB max at VOUT=0.775 Vrms; (6)thermal shut-down junction temperature, Tj: 145.
