Choosing the Right Op Amp for a Voltage Follower – What REALLY Matters!

When you're building a voltage follower (buffer) circuit, not just any op amp will do. So how do you pick the right one?

In this video, we break down the 3 most important specs to consider when selecting an op amp for a voltage follower:

✅ Dynamic Range – Can your op amp handle your signal without clipping?
✅ Slew Rate & Bandwidth – Are your high-frequency signals getting distorted?
✅ Drive Current – Is your op amp strong enough to drive your load?

We'll walk through real examples using Microchip op amps like the MCP6496 and MCP6006, explain how to read key data sheet parameters, and show you what happens when an op amp just can’t keep up.

📊 Whether you're designing a precision analog circuit or a simple buffer, this video will give you the tools and equations you need to make smart design choices.
