KA2206B

KA2206B 2.3W DUAL AUDIO POWER AMP The KA2206B is a monolithic intergrated circuit consisting of a 2-channel power amplifier. It is suitable for stereo and bridge amplifier application of radio cassette tape recorder. 12-DIPH-300 FEATURES High output power Stereo : PO = 2.3W(Typ) at VCC = 9V, RL = 4Ω . Bridge : PO = 4.7W (Typ) at VCC = 9V, RL = 8Ω Low switching distortion at high frequency. Small shock noise at the time of power on/off due to a built-in muting circuit Good ripple rejection due to a built-in ripple filter. Good channel separation. Soft tone at the time of output saturation. Closed loop voltage gain fixed 45dB (Bridge : 51dB) but availability with external resistor added. Minimum number of external parts required. Easy to design radiator fin. 16-DIP-300A ORDERING INFORMATION Device KS2206B KS22069BN Package 12-DIPH-300 16-DIP-300A Operating Temperature -20°C ~ +70°C BLOCK DIAGRAM PRE GND 7 IN1 8 NF1 9 POWER GND Fin BS1 10 OUT1 11 VCC 12 SHOCK NOISE REJECTOR INPUT AMP 1 + OUT AMP 1 RIPPLE FILTER INPUT AMP 2 + OUT AMP 2 6 R.R 5 IN2 4 NF2 Fin POWER GND 3 BS2 2 OUT2 1 BTL OUT Fig. 1 KA2206B 2.3W DUAL AUDIO POWER AMP ABSOLUTE MAXIMUM RATINGS Characteristic Supply Voltage Power Dissipation Operating Temperature Storage Temperature * Fin is soldering on the PCB Symbol VCC PD T OPR T STG Value 15 4* -20 ~ +70 -40 ~ +150 Unit V W °C °C ELECTRICAL CHARACTERISTICS (Ta = 25°C, VCC = 9V, f = 1KHz RG = 600Ω , unless otherwise specified) C...
