and its compensation capacitor is 30pF, so its maximum slew rate is 0.67V/µs. Op-amp
designers have the freedom to set both these parameters within certain limits, and this
is what distinguishes a fast, high-supply-current device from a slow, low-supply-
current one. “Programmable” devices such as the LM4250 or LM346 make the trade-
off more obvious by putting it in the circuit designer’s hands.
If i

can be increased without affecting the transconductance g

, then slew rate
can be improved without a corresponding reduction in stability. This is one of the major
virtues of the biFET range of op-amps. The JFET ...

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.
Amir M.
Data Platform Tech Lead
I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
