Делаем FM радио на микросхеме К174ХА34 (TDA7021)

Let's build a real radio receiver ourselves! :) This series of microcircuits appeared in the 1980s and was manufactured by Philips (now NXP). These microcircuits were distinguished by their easy setup and minimal components for the time. The series included the TDA7000, TDA7010, TDA7021, and TDA7088 microcircuits. The TDA7040 stereo decoder and the TDA7050 and TDA7052 low-frequency amplifiers were also produced for building a full-fledged radio receiver. In our country, these microcircuits were manufactured by various factories. Domestic equivalents: TDA7000 - K174XA42A, KS1066XA1 TDA7010 - K174XA42B, KXA060 (possibly K174XA4201B) TDA7021 - K174XA34, KR174XA34 0:00 Introduction 3:00 Features of the selected circuit and assembly 6:27 What awaits us if we take a circuit from the 1980s-90s 8:25 First power-up 9:42 Looking at the circuit from the datasheet and recalculating the circuits for a modern range 12:40 How I ended up doing it and testing
