9 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

9.1 Application Information

The TMUX6111, TMUX6112, and TMUX6113 offer outstanding input/output leakage currents and ultralow charge

injection. These devices operate up to 34 (dual supply) or 17V (single supply), and offer true rail-to-rail input and

output. The on-capacitance of the TMUX6111, TMUX6112, and TMUX6113 is low. These features makes the

TMUX6111, TMUX6112, and TMUX6113 a family of precision, robust, high-performance analog multiplexer for

high-voltage, industrial applications.

9.2 Typical Application

One useful application to take advantage of TMUX6111, TMUX6112, and TMUX6113's precision performance is

the sample and hold circuit. A sample and hold circuit can be useful for an analog to digital converter (ADC)

to sample a varying input voltage with improved reliability and stability. It can also be used to store the output

samples from a single digital-to-analog converter (DAC) in a multi-output application. A simple sample and hold

circuit can be realized using an analog switch like one of the TMUX6111, TMUX6112, and TMUX6113 analog

switches.
