So I was doing an inventory of my solid state components and found a Texas Instruments TCL272CP op amp, and I'm clueless as to possible uses and all I can seem to find are data sheets and pinouts not really anything else. if any one has done anything with it, or can help, thanks a bunch!

Are you sure about that number? I can't find it using Google or on TI's site.

the exact numbers on the IC are 09AGVCM TLC272CP

Ah,yes. In electronics letter order counts for a lot.http://www.ti.com/product/tlc272?CMP=AFC-conv_SF_SEP&partnerName=DSA

I have not used that chip, but I have used similar ones. It is a dual precision op amp with low offset and drift so it would be good for amplifying low level signals from sensors or other sources. The useful bandwidth would be in the 250-400KHz range depending on application. It also operates from a single supply (ie + and - voltages not required).

There are several application circuits in the data sheet. What were you thinking of using it for?

To be honest I'm not sure but now I think I might test out a few circuits that creat oscillations and see if I can use this amp to amplify it. To start I will use a simple 555 because that's easy to set up.

Digital really does fine with a simple relaxation oscillator - like a resistor and capacitor. So there is not much advantage to using an op amp to create a nice tidy sine wave. The primary utility of op amps these days are as pre-amplification of certain sensors and some kinds of filters.

The 555 makes a nice square wave.

Dual op amps are handy for stereo pre-amp amplification, mixing, and filtering applications as the the silicon chip is well matched for a left and right channel.
