TDA2050 Stereo Audio Power Amplifier
Posted on Monday, March 23, 2020   •   Category: Amplifiers

TDA2050 Stereo Audio Power Amplifier

This is 2x30W audio amplifier based on TDA2050 and LM1875. Amplifier PCB is suitable for both TDA2050 and LM1875 chips. Amplifier has all the necessary circuitry on board – power supply, speaker protection, delayed turn-on and fast turn-off. This is achieved using the convenient uPC1237 IC. TDA2050 and LM1875 are pin to pin compatible, the differences in their schematics are the values of a couple resistors and one capacitor. All this allows to make an universal circuit board, suitable for any of these two ICs.

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
