ICs for Audio Common Use AN7148 Dual 2.1W Audio Power Amplifier Circuit s Overview The AN7148 is an integrated circuit designed for power amplifier of 2.1W (9V, 4 Ω) 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.

Low distortion and low noise are realized and external components are very few.
