Amplificator TDA7492 2x50W – Măsurare putere, răspuns în frecvență și test semnal dreptunghiular

✔️Hello! In this episode I tested and analyzed a class D stereo audio amplifier module with TDA7492. As a bonus, I showed how to calculate the gain of this amplifier. And in the meantime I also had a surprise regarding the result. But more... see in the clip. ✔️For testing more class D amplifiers, I created a playlist:    • Amplificatoare in clasa D   ✔️And to satisfy my personal curiosity, I also made a series of episodes. In which I compared several class D audio amplifiers. I created a playlist with all 5 episodes:    • Comparare amplificatoare in clasa D   Contents: 00:00 - Introduction 00:10 - Analyzing the electronic part 02:29 - Applying thermal paste on TDA7492 03:22 - Testing on music 04:30 - Measuring and calculating amplification Av(V) 07:42 - Calculating voltage gain Gv(dB) 08:59 - Real power on 4Ω, 6Ω and 8Ω 11:41 - Efficiency on 4Ω, 6Ω and 8Ω 13:43 - Frequency response on 4Ω, 6Ω and 8Ω 18:03 - Testing with square signal on 4Ω, 6Ω and 8Ω 20:01 - Conclusions 22:05 - Some recommendations at the end 22:21 - End 📌If you liked this video, don't forget to LIKE 👍 and SUBSCRIBE ⚡
