双2.1W音频功率放大电路 Dual 2.1W Audio Power Amplifier Circuit

■Overview

The is an integrated circuit designed for power amplifier of 2.1W 9V, 4Ω output. Stereo operation is

enabled due to incorporating two amplifiers on one chip. It is most suitably used for battery operated set such as

radio cassette recorder because quiescent circuit current is small comparing to current power amplifier.

■Features

• Low quiescent current

• High operation stability

• Low radiation

• Low distortion

• Low noise

• Low shock noise from power ON/OFF operation

• Fewer external componentsattery operated set such as

radio cassette recorder because quiescent circuit current is small comparing to current power amplifier.
