Technical content

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. n Features

  • Low quiescent current
  • High operation stability
