[sdiy] The TL072

[John Blacet]

While the op amps mentioned do have some slightly better specs than the
TL074, you should look at the power draw before you start using a whole
bunch of them. In the case of the OPA2134, it's about 3 times the current
of the 074. 1.4mA vs 4 mA. If you have a circuit with 5, 4 op amp
packages, then you are going to draw 80 mA just for the amps vs 28 mA for
the 074s!
