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.
