Overview: ICs for Audio mon Use AN7149N Dual 5.3W Audio Power Amplifier Circuit s Overview The AN7149N 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 pared with power amp. current and protectors built in. As quiescent circuit current is very few, it is most suitably used for battery operated set such as radio cassette recorder. Furthermore, low distortion and low noise are realized and external ponents are very few. 12-pin SIL package enabled pact and high-densely mounted set. 5.9±0.25 7.7±0.3 7.8±0.25 ø 3.6 12 Unit : mm 29.96±0.3 28.0±0.3 20.0±0.2 0.6±0.1 R1.8 0.
