About operation amplifiers

[Crowbar]

Hi, I'm interested in sources dedicated to Op Amplifiers(theory, formulas, schemes of any op. amplifiers types)

Best regards

Hi Crowbar
You can find info:
- G.Clayton and B.Newby - "Operational Amplifiers";
- R.Coughlin and F. Driscoll - "Operational Amplifiers and linear integrated cirquits"
- www.ti.com - all for TL0xx,TLCxx........ op. amp and good manuals
- www.analog.com - all for OPxx,ADxx..... and good user guides
and GOOGLE.com
Good Luck

If you have any qestions - ask,and we will try to help

[Crowbar]

Thanks. I know a lot about Op. Amp. The main problem that there is always something interestnig in the area of OA and sometimes such novelties got missed by me

So if something unclear I can also provide some help

[Crowbar]

Hm, what can you say about using PGA202(or PGA204) in you circuits? I whant to use it as variable gain differential preamplifier for my magnetometer.

Do you know better solutions(digital gain control, fairly low noise, low offset voltage)?

[Crowbar]

Another interesting op. amp. TS512. What do you think about its characteristics?

[Carl-NC]

Probably no one has used the TS512... what did you find interesting about it?

[Crowbar]

Low noise(8nVsqrt(Hz)) with a low power consumption(~0.7 ma for dual amp), fairly low input offset voltage. Low cost. I think it's good enough. May be there are another choise for portable system active filters(low noise, low input offset voltage, low power consumption)?

Check the well known OP27, but the price could be 3 to 4x of TS512...

[Crowbar]

OP27 has more power consumption ~5mW at +-3v
