Description
The Common-Mode Input Range Calculator is tool for quickly generating plots of an instrumentation amplifier’s common-mode input range vs output. The tool is compatible with both 2-amp and 3-amp instrumentation amplifiers utilizing any supply range.
The Common-Mode Input Range Calculator is pre-loaded with specifications for TI’s most popular instrumentation amplifiers but can be modified to suit your exact application with customizable inputs for supply range, gain, and reference voltage. For a range of common-mode inputs, the tool will display the expected output voltage range numerically as well as graphically.
The Common-Mode Input Range Calculator enables designers to easily determine the input common-mode and output swing limitations of the chosen instrumentation amplifier to ensure the instrumentation amplifier operates in a linear fashion for a given design, maximizing dynamic range and minimizing prototyping time.
Features
- Preloaded with 20 of TI’s most popular instrumentation amplifier specifications
- Customizable supply, gain, and voltage reference options
- Calculator displays output limitations graphically and numerically
