"rail to rail" opamps
« on: August 26, 2012, 08:14:07 am »
hey guys and girls. does anyone happen to know if a lm358 dual opamp is a "rail to rail". if not, is there a rail to rail opamp with the same pinout in a dip-8 package. oh, and it must be able to run from 12V

Almost every (not 100% sure, maybe even any) dual op amp in a dip-8 package, has the same pinout.

You can also check out the parametric search of the manufacturer website e.g. LT: http://parametric.linear.com/operational_amplifiers_%28op_amps%29#!cols_1030,1006,1021,1023,1012,1047,1866,1367,1004,1075!s_1004,1!gtd_!1030_2!1047_yes!1075_yes

In theory, there is no difference between theory and practice. But, in practice, there is.

I think i will use the TS912 opamps because price dosentmatter that much. All specs are better anyway.

I recall some of the TS9xx opamps having a very large input current. So beware if the amplification is wrong.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.
