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