Hi All,

Interestingly OPA237 on my simulation using TINA is not working but OPA2234/LM321/OPA234 is working on TINA SPICE using this circuit.

I am now purchasing LM321 and OPA234 and OPA2234 and I will try again on bench.

I am just wondering why the…

Bell,

Below please see a simplified op amp schematic of OPA234. The reason behind a phase inversion has to do with the fact that in a normal operation emitter, Ve, follows the input, Vin, but collector of the input transistor, Vc, should be always 180…

Hi Thiago,

Sorry for the long delay to my reply...just getting back into the swing following the Holidays.  I have several comments/concerns regarding your design...

• I would like to point out to you that the OPA704/OPA705 is a 12V opamp, with ABS MAX…

Hello Paddy,

What is the total supply voltage?  It's a little hard to tell.  If it's 12V or below, look at the OPA735 for the precision amplifiers, for 36V operation, look at the OPA188 for the precision parts and OPA234 for the more generic amplifiers…
