Hello,
I am attempting to build a 0 to 10v analog output driver. Most of the time there will be less than 20mA loads on the output (the output will either be wired directly to a separate analog-to-digital converter, or an inductive load). I want it to be capable of handling 100mV minimum. The output will not change faster than 100Hz.
The LMC7101 looks to be a good op-amp for this. I attempted to add some simple circuit protection, and a capacitor to smooth the output out slightly. Is this a good way of accomplishing this? I want it to reasonable robust and not damage too easily. (There may be some EMI/EMF nearby as well). The absolute accuracy of the output is not very critical, e.g. it could be off by 2% and its no big deal.
So this was my attempt at it, does this look good, or should I change anything? Thanks and any help is greatly appreciated!
p.s. the capacitors C16 (100pF) and C17 (10uF) I just chose - I couldn't figure out how to correctly calculate these. Same thing goes for R3 (33 ohm resistor on output).
