Question of the Day by Adhiraaj Ghosh I am using CD4051 analog - TopicsExpress



          

Question of the Day by Adhiraaj Ghosh I am using CD4051 analog multiplexer IC for interfacing it to an ADC.I have provided +-5 volts to Vcc and Vee pin and Gnd to ground pin as I have bipolar input signals. As per datasheet ON state resistance of a channel is 125 ohms. I am facing voltage drop between input and output and this drop is increasing with increasing input voltage. 30mv, 50mv, 110mv and so on till 5 volts max. Note that ADC is connected to Mux o/p while observing this in system. How to avoid any drop OR how to get constant drop that can be compensated later? please reply.
