TDA7000
« on: October 22, 2013, 04:05:32 pm »
Hello!
I have built TDA7000 fm receiver, but it drifts, sometimes it seems that it locks little bit, but then it drifts away.
I have used this schematic, just with pin 1also connected threw 2.2k to +5.
Instead of Bf94 i used bf199 and BB329.

What part of the circuit should i be testing?

Thanks!

Your schematic is in error regarding freq. control and also the regulator circuit pins are vague.
Download the datasheet for the TDA7000.
