This integrated circuit is designed for power amplification of 5.3W audio output. It incorporates two amplifier circuits on a single chip to enable stereo operation. It achieves high reliability through a smaller quiescent current and built-in protectors. As the quiescent current is very small, it is well-suited for battery-powered devices like radio cassette recorders. It realizes low distortion, low noise, and requires few external components.

`The AN5277 is an integrated circuit (IC) amplifier widely used in audio applications, offering excellent audio quality and performance. Designed specifically for audio amplification, the AN5277 provides a compact and efficient solution for various audio systems, including portable devices, multimedia speakers, and automotive audio systems.
1. ICs for Audio Common Use
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
