AN7147N
Dual 5.3W Audio Power Amplifier Circuit
s Overview
The AN7147N is an integrated circuit designed for
power amplifier of 5.3W (12.0V, 3Ω) output. Stereo oper-
ation is enabled due to incorporating two amps. on one
chip. It makes high reliability by smaller quiescent current
compared with power amp. current and protectors built in.
As quiescent circuit current is very small, it is most suit-
ably used for battery operated set such as radio cassette
recorder. Furthermore, low distortion and low noise are
realized and external components are very few. 12-pin
SIL package enabled compact and high integrated set.
s Features
• Low quiescent current
• High operation stability
• Low radiation
• Low distortion
• Low noise
• Low shock noise from power ON/OFF operation
• Fewer external componetns
