Hello Everyone,
In my system I have 8 sensors connected to 8 lines of analog Mux(4051) and one amplifier is connected at the output of Mux. Also the output of Amplifier is connected to PIC.
I am using PIC16F871 to scan the 8 lines.
I am using 4MHz crystal. Here if I connect 0.5V (DC) as the input at one of the 8 lines, It gets amplified and PIC can see signal at the I/P lines.
but if I connect sensors it does not work. I even checked the sensor output at the amplifier output and it shows 5v.
I used Digital Mux before and it worked perfectly and now when I switched to Analog Multiplexers it does not work.
Do I need to connect anything extra to make the Analog Mux work with my PIC?
Kindly let me know if something is not clear.
Regards,
