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 V DD = 37.5 V, V SS = –12.5 V). The TMUX7612 supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from V SS to V DD.
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.
