I am looking for an opamp that can drive as a DC reference 2.5V C load 200nf, load current uA supply voltage 3.3V. Opamps that are stable at any Cl would be of interest.
Apologies for responding late. We have LTC products that do have the ability to drive large capacitive loads. However, non can be powered up with your given supply range. The lowest is +/-2.5V which you can use for single supply 5V, GND. The IVR will also be tight with the given supply GND + 1.6V, and VS - 2V. Below are our LTC op amps that can drive high C-loads.
These products can drive large capacitive loads with the cost of overshoot. Below are the graphs of the overshoot of the parts.
With that given take your highest frequency, peak amplitude, etc. and calculate how much speed your cap charge and discharge.Regards,Goz
