I have a 2.5V DAC with two channels.
I invert one of these with OpAmp.
So I get:
Channel A: 0V to 2.5V
Channel B: -2.5V to 0V
I would like to have an output on which I can switch these 2 channels at a frequency of 0.5MHz.
I plan to use this to generate a signal for a current source.
Now I use TS12A12511 analog switch to switch DAC channels, but it is very noisy.
It is very important for me to have a good signal quality, but I can't figure out what else to do.
