About this product
An 8-channel analog multiplexer and demultiplexer in a SOP-16 package, controlled by digital select inputs. It acts as a digitally controlled analog switch with low ON impedance and very low OFF leakage. It lets one analog input or output be shared among several signals, such as reading multiple sensors through a single ADC pin.

Frequently asked questions
Can I use it with an Arduino to read more sensors?
Yes. Select the channel with the digital select pins, then read the common output with one analog input. The 4051 family uses three select inputs plus an inhibit (enable) input.
Does the analog signal have to stay within the supply?
Yes. Keep analog signals within the supply rails and check the datasheet for the allowed supply and signal ranges before designing the circuit.
