Texas Instruments - Capacitive Touch Sensors, Proximity Sensor ICs

Texas Instruments is a semiconductor company.
In 1930, Texas Instruments was founded in Dallas, Texas, USA. The company's products mainly include high-performance analog chips, digital signal processors, microcontrollers, and various connection and power management solutions. Texas Instruments' products have the following characteristics: high performance, low power consumption, high reliability, easy integration, and wide application flexibility. The company's products are widely used in fields such as consumer electronics, automotive electronics, industrial control, communication, medical electronics, aerospace, and military defense.
Texas Instruments has acquired Spansion's manufacturing division and Chengdu Chengxin Semiconductor. In 2011, the company acquired National Semiconductor.

Capacitive Touch Sensors and Proximity Sensor ICs are common sensing technologies in modern electronics that use changes in capacitance to detect the presence and location of a target object without physical contact. Provides innovative solutions for user interface design and automation control. Capacitive Touch sensor is an electronic device that works based on the principle of capacitance, which recognizes the touch action by detecting the change of capacitance between the object and the sensor. Its core is to use the electric field change generated when the human body or object is close to, resulting in the change of the sensor capacitance value, and then converted into electrical signals for processing. Proximity Sensor ICs is an integrated circuit designed to detect the proximity of an object. By transmitting and receiving specific forms of energy (such as infrared, ultrasonic, or electromagnetic fields), it analyzes the time and intensity of the signal return to determine the distance and position of the object.
