DESCRIPTION
LI NEAR I NTEGRATED CI RCUI T
1.2W AUDIO POWER AMPLIFIER
The UTC820 is a monolithic integrated circuit audio amplifier. It is designed for audio frequency Class B amplifiers.
FEATURES
- Wide operating supply voltage:Vcc=3~14V
- Low quiescent supply current(Icc=4m A,typical)
- Medium output power Po=1.2W at Vcc=9V,RL=8ohm ,Thd=10%
- Good ripple rejection
- Minimum number of external parts required.
