I am using part #:ADG732. I have connected the input of the mux to a current pulse (+/-100uA). The outputs are each connected to 10Kohm resistors, which are the connected to ground. I use a microcontroller (MSP430) to control the select lines of the mux. The signals generated by the microcontroller are directly connected to the select lines of the mux.
When I look at the output of the mux on the oscilloscope across the 10kohm resistors, I see spikes every time I switch on and off from that channel
I have attached an output signal across the 10kOhm resistor from one channel of the mux. It shows a spike occurring every time I switch on and off to and from this channel. I have also zoomed in on the spike and attached a photo of that as well.
Do you have any idea why is spike is occuring and how I can remove it?
