Dilshan Jayakody has published a new build: This is simple, but very high quality CXA1191S based FM radio receiver system. In this design we use Sony CXA1191S as FM tuner and TDA2003 as an audio amplifier. This receiver system is designed to work with 12V DC power source and it delivers approximately 6W audio output […]

Low cost TEA5767 based FM stereo radio receiver
Dilshan Jayakody writes: TEA5767 is electronically tuned FM stereo radio receiver from NXP for low voltage applications. TEA5767 based radio modules are now common in the field and this project is based on Samsung TT-502 radio module. The main objective of this project is to design low cost FM tuner based on this TT-502 / […]
CD2003 – yet another simple FM radio receiver
Dilshan Jayakody writes: In last few days we are looking for some simple FM radio receiver to integrate into one of our ongoing project. For that we try several FM radio receiver ICs including TDA7000, CD2003/TA2003/TA8164, CXA1019 and KA22429. Out of all those chips we select CD2003 (or TA2003/TA8164) based receiver for our project because of […]
Arduino solar radio
Simon built a solar powered Arduino FM receiver. Using a solar panel to charge the batteries, this Arduino controlled device can work without the need to recharge. A SI4073 FM tuner ICs output is connected to a TDA7051 integrated amplifier, while the Arudino controls the channel selection of the FM tuner. There is a multi-position switch used […]
