Texas Instruments TMUX7612 4-Channel Precision Multiplexers
Texas Instruments TMUX7612 4-Channel Precision Multiplexers are Complementary Metal-Oxide Semiconductor (CMOS) switch devices featuring four independently selectable 1:1 Single-Pole, Single-Throw (SPST) switch channels. These modules work with a 4.5V to 50V single voltage supply range, ±4.5V to ±25V dual voltage supply, or an asymmetric dual supply such as VDD = 37.5V, VSS = 12.5V. The series supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from VSS to VDD. The switches are controlled with appropriate logic control inputs on the SELx pins, and the special architecture enables ultra-low charge injection. This feature helps prevent unwanted coupling from the control input to the analog output of the device and lowers AC noise and offset errors.
Typical applications include semiconductor test equipment, Solid State Relay (SSR), photorelay replacement, Programmable Logic Controllers (PLC), factory automation and control, and Data Acquisition systems (DAQ).
