3 Description

The TMUX6612-Q1 is a complementary metal-oxide

semiconductor (CMOS) switch device with four

independently selectable 1:1, single-pole, single-throw

(SPST) switch channels. The device works with a

single supply (4.5V to 36V), dual supplies (±4.5V

to ±20V), or asymmetric supplies (such as VDD =

20V, VSS = –10V). The TMUX6612-Q1 supports

bidirectional analog and digital signals on the source

(Sx) and drain (Dx) pins ranging from VSS to VDD.

The switches of the TMUX6612-Q1 are controlled with

appropriate logic control inputs on the SELx pins.

The TMUX6612-Q1 features a special architecture

which allows for ultra-low charge injection. This helps

prevent unwanted coupling from the control input to

the analog output of the device and reduces AC noise

and offset errors.
