Sensor interface and excitation IC chips are used as interfaces to sensors and other devices. The input at the interface collects data from the sensor and the output of the interface sends the data to a computer or other suitable device. IC is an acronym for integrated circuit. Sensor interface and excitation IC chips are integrated circuits (IC) that may also provide signal compensation and temperature correction in a variety of sensors. A sensor interface IC chip is used in many industries, including automotive, robotics, manufacturing, and medical applications.
