KA2201
1.2W AUDIO POWER AMP
INTRODUCTION
The KA2201 is a monolithic integrated audio amplifier. It is designed
for audio frequency class B amplifier.
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.
