hi all, i am using HEF4051 as address decoder and to send analog voltage through that channel now what i am doing is to send address bit and after that some analog voltage to be sent in that channel. i need to use all the channel simultaneously so connected capacitors to hold the value for few milliseconds. i first send address bit after that analog voltage and then address of next channel and its analog value and keep on doing it in a loop.Thus all values get refreshed after a particular time interval.
Now my problem is that when i do so i didn't get the voltage retained by capacitors. After some efforts i got voltage to be retained but it is the average voltage of the channels not the needed voltage, So can anyone explain this why is this happening and solution as well. thanx in advance!!!!!
