Hi,
I need to design a analog mux with 2-4 small voltage (about 1.3v) inputs, and only one output which does read the one input at a time, very thanks for help. Thank you!
Thanks for the reply. Sorry that I didnt mention that I am doing the chip design, so that I need to design this analog mux in CMOS circuit, my understanding so far is that it is like some switched current circuits, could you give me some hints on the designing? Thank you in advance~
Take a look at some existing designs.
The 4051 is but one of many designs.
Dallas/Maxim has quite a variety of analog multiplexers. So does Analog Devices.
Find several models that are reasonably close to your requirements, and look at their schematics. Then design something that is optimized for your requirements.
