App note: Selecting the right CMOS analog switch

App note from MAXIM Integrated digging on the basics of CMOS analog switches and the latest improvement on them from the standard one. Link here Integrated analog switches often form the interface between analog signals and a digital controller. With the large number of analog switches on the market today, there are many performance criteria […]

App note: Interfacing to analog switches: Driving the control input of an analog switch with 1.8 V or lower − Is it safe?

ON Semiconductor’s analog switches let you drive with an input control voltage lower than Vcc. Link here (PDF) Analog switches are everywhere today. Due to their small size and low current consumption, they are popular in portable devices where they are effective in a variety of subsystems including audio and data communications, port connections, and […]

App Note: Analog switch multiplexes SFP modules

rsdio writes: There is probably a way to implement this circuit with any analog mux instead of the Maxim part… Analog Switch Multiplexes SFP Modules To avoid multiple I²C bus masters in a telecom or data-communications system with SFP modules, add an analog multiplexer (MAX4572) that directs the data line to the appropriate SFP module.
