Summing Amplifier Explained: Add Voltages with an Op-Amp ⚡

Video Description

📌 YouTube Description Want to add multiple signals together without using a microcontroller? In this video, we’ll break down summing amplifiers—one of the most practical and powerful applications of op-amps. 💡 You’ll learn: What a summing amplifier is and why it’s so useful in electronics How op-amps perform real-time analog computing (addition, scaling, averaging) Step-by-step analysis of the inverting summing amplifier circuit Real-world examples, from combining sensor outputs to audio mixing How you can build this circuit yourself for under $1 using just one op-amp and a few resistors We’ll go from basic concepts to circuit analysis, all explained clearly with visuals—perfect for electronics beginners, engineering students, and hobbyists. 🔎 If you’re new to op-amps, check out our Op-Amp Basics Playlist here: https://www.youtube.com/playlist?list=PLfox_rt4mFCL94d_hcqqFCABmmup9VI9K 📚 Topics covered: Op-amp closed-loop operation Negative feedback explained Summing amplifier equation & example problems Analog vs digital approaches Practical design tips for your own projects 🎥 More tutorials you’ll love: Inverting Amplifier Explained → https://youtu.be/JE36D-Ffwvc?si=xs6CJdcu_U_JrVpb Non-Inverting Amplifier Tutorial → https://youtu.be/eqHyhg8aTrs?si=tRMZnFUQinJd1cwA Comparator Circuits with Op-Amps → https://youtu.be/d6670gSIbiM?si=92rEWyc40hh0Hopx 👉 Don’t forget to like, share, and subscribe for more electronics tutorials and exam-focused problem breakdowns. 🙏 Support the Channel If you found this video valuable, you can support us on Patreon: https://www.patreon.com/ProfMAD Every contribution helps us make more high-quality tutorials like this. #Electronics #OpAmp #SummingAmplifier #AnalogComputing #Engineering #Circuits
