Typical Application

Many analog front end data aquistion systems are designed to support differential input signals with a wide range of output voltages. In systems where the output sensor is separated from the rest of the signal chain by long cables, a high common mode voltage shift may be superimposed onto the signal lines. One solution to this problem is to use a high voltage multiplexer in combination with a high voltage op amp level translation stage to properly scale the input signals to the correct input requirements of the ADC. The TMUX8109 allows the system to be designed for a differential, four channel, multiplexed data aquisition system.
