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 (4.5V to 50V), dual supplies (±4.5V to

±25V), or asymmetric supplies (such as VDD = 37.5V,

VSS = –12.5V). 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.
