Dave Jones's long introduction to op-amps covering the basic rules, virtual ground, common configurations and part selection; recommended to learners who found textbook treatments hard going.
Dave Jones builds peak detectors from a simple diode and capacitor up to precision op-amp versions; a frequent reference for envelope and pulse detection projects.
Alan Wolke gives a gentle introduction to the BJT differential pair and how it forms an op amp input stage; people build and simulate along with it.
Explains how to bias a transistor stage so the operating point does not depend much on the device's beta, using feedback.
A practical tutorial on phase locked loops that people link when someone needs to see a PLL such as the NE567 working rather than read theory.
Covers how an op amp's gain bandwidth product and slew rate limit a closed loop circuit, used to explain unexpected bandwidth results.
Recommended for its 3D animation of how an op-amp behaves, credited with helping students picture the device during a first circuits course.
A tutorial on passive RC high pass filters, recommended as the step for stripping DC offset or low frequency noise out of a microphone or sensor signal.
An Afrotechmods explainer on peak detector circuits, repeatedly suggested to people trying to capture the maximum level of an audio or sensor signal.
Offered as a dedicated playlist for learning how op-amps work and how to use them in circuits.
