3 Description

The TMUX7612 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 = –12.5 V). The TMUX7612

supports bidirectional analog and digital signals on the

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

VDD.

The switches of the TMUX7612 are controlled with

appropriate logic control inputs on the SELx pins.

The TMUX7612 features a special architecture which

allows for ultra-low charge injection. This feature

helps prevent unwanted coupling from the control

input to the analog output of the device and reduces

AC noise and offset errors.

The TMUX7612 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.
