Strange op-amp circuit FM radio Ask Question.

CD2003—AM/FM radio monolithic integrated circuit

In last few days we are looking for some simple FM radio receiver to integrate into one of our ongoing project. Maybe the potmeter is not a logarithmic one like you would normally use for audio. This SAW filter is already a filter by itself in one component. Leave a Reply Click here to cancel reply.

Yet another link to a project which uses unobtainable or at least difficult to source components.

It’s a CE stage Common Emitterpart of the output signal is fed through vatasheet k resistor back to the input. The signals received from Antenna input from the CD 16 pin ,mixing with the LO signal in the mixing circuit. CF1 is a ceramic filter rather than a SAW device. Post as a guest Name. Becauce CD will not easily damaged,we should pay attention to the datasheeet of its three-terminal filters to be checked.

Email Required, but never shown. Correct and there’s also another advantage to a bridge, you datzsheet need a large output capacitor for the speaker. Some reported it to have better reception than TEA After being converted by datasyeet IF amplification, detection, electronic switch, the signals output from 11 pin to reach the post-stage circuit.

There are 2 resistors connected to the collector of theand there is a biased resistor k connected in between. One more nicely done radio with TEA C16 couples the inverting inputs datassheet the audio amplifiers together for AC signals. Always worth a try! I also found a wiki entry: January 8, at 4: Learned few new things, and got some questions, especially the output stage. That Crystal filter consists of many resonators to make a filter.

datashfet BrianDrummond According to muRata, see: Not how R6 is 10 k but the potmeter is 50 k. Yes you can use a ceramic cap also as long as it is also 10 uF.


Table 1 CD integrated circuit pin functions and typical operating parameters Table 2 CD integrated circuit pin functions and test data on the desheng multi-band radio 3. Sign up using Email and Password.

May 20, at R6 has probably to do with the volume adjust.

Built the circuit and it works very well. Funny thing is it has TEAcompatibility mode. Recent Comments Bill F: Google doesn’t show any detail information as well. ChrisR 4 6. May 20, at 2: May 19, at 7: The Op-amp is a dual op-amp, but the output is only mono. Exactly the same way as when using feedback with an opamp. Rohit, that is great, congrats. I am working on a simple FM radio receiver. May 19, at 5: The signals received from Antenna input from the 1 pin after being band-pass filtered by the BPF,added to the mixing circuit after HF amplifier.

Mixing with the LO signal in the mixing circuit,the signal obtained output from 3 pinobtaining the
