Hello,
I am trying to make an analog signal from 0V-1V. By that I mean, I want to have a real 0V without noise in it. I can control the offset by using a offamp buffer, but I would like to control the noise output. I was able to reduce it a bit by using a capacitor to the gnd at the input signal, but not as much as I would like to reduce, currently the max and min noise is around 9mV to -11mV. What is an acceptable noise for a 0V signal?
I heard that the easiest way is to have a driver with double control (TTL + Analog). With the TTL signal, we can create a real 0 (whatever is your control signal).
Can someone enlighten me with a test schematic for this kind of driver?
thanks
