Is there an Analog Devices, Rail-Rail (input and output) operational amplifier that will drive an unlimited load capacitance?
Is there also spice model.
We have some rail to rail parts such as ADA4807 and ADA4805 and it's capacitive driving capability is defined.
Most data sheets have specifies Capacitive Load Drive Capability and other provides "small signal over shoot vs. capacitive load" plots.
To avoid oscillation cause by capacitive load, there are several ways to stabilize your circuit.
You may check this link to see some of the methods.
Thanks and regards.
