Part Number: OPA863A Other Parts Discussed in Thread: OPA2863A Is there a Pspice model for the OPS863A. I can find a model for the non-A version, but is this close enough to use for the A version? There are several parametric differences between the two…
You can use any rail-to-rail opamp. Section 3.1 shows how to choose an appropriate resistor.
(Why did you choose the OPA350? Using a 10 V opamp like the OPA863A would be simpler and save power.)
Hi Ann,
Here is a link to a comparison table for the OPA863, OPA863A, and OPA625: https://www.ti.com/compare-products/?id=72&type=GPT&partList=OPA863A,OPA863,OPA625&columnList=89,480,1261min,1261max,23typ,512,511,22typ,967typ,7typ,1typ,2max,78,2192,1498…
Hello Robert,
Thank you for your quick response. So the configuration would be a split supply +/- 3.25 V, input centered at ground.
Does your customer require radiation hardening or space-grade packages?
I also have a couple higher voltage op-amps to…
BTW, for some of the circuits, we can skip the OPA355NA/3K, and use the OPA863A, but that doesn't help the voltage rail accuracy since we do have several OPA355NA's in the circuit.
