3 Description

The TMUX7612-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 (4.5 V to 50 V), dual supplies

(±4.5 V to ±25 V), or asymmetric supplies (such as

VDD = 37.5 V, VSS = –12 V). The TMUX7612-Q1

supports bidirectional analog and digital signals on the

source (Sx) and drain (Dx) pins ranging from VSS to

VDD.

The switches of the TMUX7612-Q1 are controlled with

appropriate logic control inputs on the SELx pins.

The TMUX7612-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.

The TMUX7612-Q1 is a part of the precision switches

and multiplexers family of devices and have very low

on and off leakage currents allowing them to be used

in high precision measurement applications.
