| KA2201 INTRODUCTION The KA2201 is a monolithic integrated audio amplifier. It is designed for audio frequency class B amplifier. 1.2W AUDIO POWER AMP 8-DIP-300 FEATURES * Wide operating supply voltage: VCC = 3V~ 14V * Medium output power. PO =1.2W at VCC =9V, RL =8, THD = 10%. * Low quiescent circuit current (ICCQ = 4mA: Typ). * Good ripple rejection. * Minimum number of external parts required.
