We design our receiver based on Toshiba TA datasheet and later we try TA and CD with same circuit. Either CD or TA CDGP Datasheet PDF – FM/AM RADIO IC – WUXI CHINA, CDGP pdf, CDGP pinout, Other data sheets within the file: CD Pinouts: CDGP datasheet.

Same thing different names. Becauce CD will not easily damaged,we should pay attention to the periphery of its three-terminal filters to be checked. The Op-amp is a dual op-amp, but the output is only mono.
Reprinted Url Of This Article: Yes you can use a ceramic cap also as long as it is also 10 uF. The opamp outputs are connected as a ‘bridge’. I also found a wiki entry: Learned few new things, and got some questions, especially the output stage. R6 has probably to do with the volume adjust. The caps cause a degree phase change in the inputs, and the outputs are therefore degrees out of phase as well. Always worth a try!
Post as a guest Name. Note how the bottom pin of CF2 is actually connected to the positive supply rail, the other pins are input and output. Leave a Reply Click dattasheet to cancel reply. CF1 is a ceramic filter rather than a SAW device.

Code is shared on Github: SAW filters can be expensive, also we have full on-chip solutions these days so you won’t see many SAW filters in modern products. Gave it a minimalist switch to toggle the channels stored in an array.
Crystals are more expensive and placing a resistor in series with a crystal deteriorates it’s properties. May 20, at 2: To evaluate my Code: But if I’m wrong please explain the difference as I could not find any. It reduces the gain of that stage but improves linearity and bandwidth. Email Required, but never shown. All files are avaialble at elect.

May 19, at 5: You can also subscribe without commenting. The signals received from Antenna input from the 1 pin after vd2003 band-pass filtered by the BPF,added to the mixing circuit after HF amplifier. BrianDrummond According to muRata, see: Some reported it to have better reception than TEA Not how R6 is 10 k but the potmeter is 50 k.
I am working on a simple FM radio receiver. After being converted by the IF amplification, detection, electronic switch, the signals output from 11 pin to reach the post-stage catasheet.
According to the above-mentioned signal flow ,it’s convenient to repair AM or FM radio with sound or radio trouble. May 20, at Correct and there’s also another advantage to a bridge, you don’t need a large output capacitor for the speaker.
The speaker doesn’t connect to the ground in this setup, Very strange.
