AN7147N

Dual 5.3W Audio Power Amplifier Circuit

■ Overview

Unit : mm

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.
