Lecture 27 | Introduction to Comparators | Op Amp

In this video, we introduce Comparators using Operational Amplifiers (Op-Amps). You’ll learn what a comparator is, how an op-amp works as a comparator, and why it is widely used in electronics and instrumentation. 🔹 Topics covered in this video: • What is a Comparator? • Op-Amp as a Comparator • Inverting and Non-Inverting Comparator • Zero-Crossing Detector • Comparator Output Characteristics • Difference between Op-Amp and Comparator • Practical applications of comparators 🔹 Key Applications: ✔ Zero crossing detectors ✔ Voltage level detectors ✔ Over-voltage and under-voltage protection ✔ Analog-to-digital conversion ✔ Wave shaping circuits This lecture is very useful for undergraduate students of Physics and Electronics, especially for BSc, MSc, BTech, Diploma, and competitive exams. 📌 Watch till the end for clear concepts and easy explanations! 👍 Like | 💬 Comment | 🔔 Subscribe for more Electronics & Physics lectures
