Hey all,
i was messing around on a spice program with the TLo72 opamp, and i dont get the whole dual opamp. Is it just two opamps in one, completely isolated from the other?
Thanx 4 input,
Alex

completely isolated, only sharing the V+ and the V-
(in real life; don`t know if there is some cross-talk or thermal issues implied in the spice-model, though...)

Thx,
and also, what is the difference between the TL072, and the TL072CP?
I cant find in anywhere on the net...

dunno bout CP, but at ST components a C denotes a smaller temp-range (0-70degC), compared to (-40 - 105)..

Quote from: Alpha579what is the difference between the TL072, and the TL072CP?

In that case, the C stands for commercial temperature range as Puretube stated, and the P stands for plastic DIP package. Remember that the prefix and suffix letters are specific to each manufacturer. That part is from TI I'm guessing.

Here is one copy of the TI datasheet (http://www.renderedelement.com/documents/TL071.pdf). Always try looking at the datasheet for the chip's maker for more info.

Take care,
