10 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. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

The TMUX611x family offers outstanding input/output leakage currents and ultralow charge injection. These

devices operate up to 33 (dual supply) or 16.5V (single supply), and offer true rail-to-rail input and output. The

on-capacitance of the TMUX611x is very low. These features makes the TMUX611x a family of precision, robust,

high-performance analog multiplexer for high-voltage, industrial applications.

10.2 Typical Application

One useful application to take advantage of TMUX611x family'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 TMUX611x analog switches.
