(Pack of 10) TL072CP DIP8 Delay Op Amps Operational Amplifier IC Chips

Worked in a delay build, only time will tell on month 4

I only needed two of these, but this was the best deal I could find. I've used one so far in a guitar pedal build and it turned out pretty good. I hope the rest of them are just as good.

I have ordered this product before, and I'm very pleased with it's performance. I build guitar effects pedals and amplifiers and I use this item a lot.Very reliable and good price also.

Every single one works perfectly.

If you want TL072CP op amps, look elswhere.If you need any old general purpose op amp you can get them for a lot less..I have no idea what these actually are, but they test out with a 0.4V/microsecond slew rate. That is as bad or worse than a 741 or 324. At this speed I didn't even bother to check the input current to see if they were actually have JFET inputs. They are useless for the intended application.A TL072 should have slew rate of 10 to 13 Volts/uSec. It is a high speed op amp.

Hope they work!
