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.
