双5.3W音频功率放大电路 Dual 5.3W Audio Power Amplifier Circuit

■Overview

The is an integrated circuit designed for power amplifier of 5.3W 12.0V, 3Ω output. Stereo operation 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.

■Features

• Low quiescent current

• High operation stability

• Low radiation

• Low distortion

• Low noise

• Low shock noise from power ON/OFF operation

• Fewer external componetns
