Samsung KA2201 Datasheet
KA2201 1.2W AUDIO POWER AMP
INTRODUCTION
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 (I
• Good ripple rejection.
• Minimum number of external parts required.
