Hi Sue,
The difference is shown below on the right Y-axis of the phase scale between the Rev. A and the Rev. C revision. In addition, the Figure 6-7 is allocated on page 11 in the latest C revision.
If you have additional questions, please let us know…
Yes, it is possible that in the midst of transition between P and N-channel input differential pairs, around Vcm=(V+)-0.7V, the OPA391 offset may be in fact up to +/-2.5mV as shown on your graph below.
However, there is nothing in the OPA391 datasheet…
Part Number: OPA391 Other Parts Discussed in Thread: LM7705 Hello Experts!
I'm working on a project where I use an op amp to gain a strain gauge signal into an ADC. The OPA391 is my top pick for my ADC preamp. A rough block diagram:
For this project…
Part Number: OPA391 Hi team,
What does "Output short circuit" absmax mean and what does "continuous" capability mean?
OPA391 shows its absmax output short circuit as "min: continuous" and "max: continuous". On the other hand, TLV900x…
Part Number: OPA391 Other Parts Discussed in Thread: LMP7721 Hi E2E,
Our customer would like to use the op-amp in a buffer configuration to condition the output of a high impedance source. They required the probe to be hot-swappable, where the non-inverting…
Part Number: OPA928 Other Parts Discussed in Thread: OPA328 , OPA392 , OPA391 Hi team,
We are now promoting our OPA928 to replace ADI's ADA4530-1ARZ-R7.
Could you please kindly help check is OPA928 the best choice?
And when will OPA928 RTM?
Thanks,
…
Part Number: DAC8564 Other Parts Discussed in Thread: OPA333 , OPA317 , OPA391 , OPA191 , XTR111 , XTR300 HI SIR
I want to design a 4-20mA Function which use the DAC8564,
Did you have suggestion AMP for this?
thanks

I would like to ask you to tell me CMOS or JFET OPamps which have very high input impedance.
I would like to know the OPamps which have the impedance around…
Hi Rajesh,
You could use the OPA391 or cost-down option OPA396. The AOL is specified for output swing 100mV from either rail for light loads.
In this case, you can swing from 0.1V to 3V for your ADC input voltage.
See updated circuit below.
