Hi All,
I have a doubt about what is the best design practice for the following circuit:
let's assume I want to use the AD4550 as voltage reference for an LDO, what is the best way to make the circuit "calobrable"? For example, after some months the long term drift of the reference is not acceptable anymore, how can you tune it?
My idea is to take a reference with a voltage higher than what i need and then use a resistive divider, in order to be able to tune the resistors in future.. but this adds another soure of drift and may redure the intervals bethween calibrations.
Any application note or advice?
Thank you
