I need help selecting a MUX for using with LTC2380. At least 2 differential bipolar channels are required. Signal BW is about 100KHz. I've made a design with the help of Analog Precision ADC tool:
The tool is suggesting ADG1209, but according to its datasheet it has (0.15% or -56.5dB THD) and that is much worse than the whole system at 100kHz.
I was also looking at ADG409 and it's datasheet doesn't mention anything about distortion. Should I believe it's so low it can be disregarded?
