Forum Post: RE: Inquiry regarding voltage output swing on OPA192
Atsushi,In addition to 2k and 10k load, the output voltage swing of OPA192 is also specified for NO LOAD (10mV from rail) that would be virtually the same as the swing with 100k load or greater-see...
View ArticleForum Post: RE: Using INA122 for nulling other amplifiers.
Hello Smiffy,If the application requires the output swing to include or go below ground, a dual supply is necessary. Put another way, with a single supply the output of the INA122 can only come to...

Marek, Thanks for the reply, I'll give both parts serious consideration. OPA192 is incredible; I didn't know we could make amplifiers that good. That part didn't come up on Digikey's parametric...

Thanks, Pete. I'll go the dual supply route - it's only a case of adding a second battery snap.

Forum Post: RE: Input offset voltage of OPA2140 and OPAx192
Ryuji,What you refer to in your question is a typo - both, the input voltage offset and offset drift, are centered around zero and thus should have +/-sign in front of them; therefore, the table below...

Hi Bob,The LMC6xxx series does have asymmetrical sink/source gains. It is the nature of the beast.With light loads (>100K), the gains could easily surpass 130dB (I was measuring in the mid 140's at...

Forum Post: RE: Thermal transient behavior of INAs and OPAs
Kavindu,Overshoot in INA's and op amps is closely related to the phase margin (see below), which in turn is a function of the bandwidth: BW=gm/Cc=Itail/(Vt*Cc) where current in the input stage,...
