I am looking for multiplexer to use for high speed data sampling for low amplitude time varying signals. Unfortunately, there is not a lot of documentation about multiplexers and I have observed behaviors of the few I've tried that were not mentioned on the datasheet.
How can I model a multiplexer? I understand there is some R_on and Capacitance, how can I begin drawing that?
Does anyone know of good simulation files for LTSpice (or something) for multiplexers?
Does anyone know of a very accurate and high speed muxer good for mV analog signals?
The ones I've tried seem to have a transient response that squashes the signal if it is under 200 mV, but I'm trying to avoid amping it pre-mux.
Thanks!
