I've built a 16 channel DAQ board using an mbed and the TI HC4067M to switch each sensor to the ADC on the microcontroller. I'm getting a decent amount of crosstalk if I switch channels much faster than 500us. For example if I attach a few pressure sensitive resistors to the board, the voltage from the resistor I press on bleeds into adjacent channels. Ideally I'd like to be able to sample each channel at a minimum of 1000Hz as some of the inputs come from an EMG with analog outputs. What would be the best mux for this case?
