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.
