“This tuner circuit is a quick prototype which I built to test the RDA5807M FM radio tuner IC. RDA5807M is a single-chip tuner IC with RDS and MPX decoder, and it equipped with I2C interface for control. The main reason …
Content for AN7147N
The AN7147N 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 suitably 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.
