描述 Description

The TMUX6612-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 (4.5V to 36V), dual supplies (±4.5V to ±20V), or asymmetric supplies (such as VDD = 20V, VSS = –10V). The TMUX6612-Q1 supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from VSS to VDD.

The switches of the TMUX6612-Q1 are controlled with appropriate logic control inputs on the SELx pins. The TMUX6612-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.
