Working Principles

The TC7116CKW713 is an integrating analog-to-digital converter that uses a successive approximation technique to convert analog signals into digital data. It employs an internal voltage reference to establish the conversion range and compares the input signal against this reference. The converted digital output is then displayed on a 3.5-digit seven-segment LED display.

Detailed Application Field Plans

1. Digital Multimeters: The TC7116CKW713 is commonly used in handheld or benchtop digital multimeters for accurate measurement of various electrical parameters.
2. Process Control Systems: It finds application in industrial process control systems where analog signals need to be converted into digital data for monitoring and control purposes.
3. Portable Instruments: Due to its low-power operation and compact size, it is suitable for portable instruments such as battery-powered voltmeters or thermometers.
