Capacitive touch - GTX314L chip is interactive touch screens education one of the GreenTouch3LPTM capacitive touch product sensor series with memory function, power over temperature, over current protection, can withstand repeated keystrokes. At the same time, this intelligent chip with 0.1 seconds to touch touch panel response speed, but does not cause wrong operation, its precise touch experience.
GTX314L can test capacitance has 14 channels under interactive panels for education green touch 3 LPTM engine operation. Due to the green touch 3 LPTM low power engine, application of various battery can increase the using time of the product. Also based on the existing GreenTouch3TM engine technology, can ensure the reliability of all kinds of noise and environmental change.
Internal control register interface can use I2C, digital interactive whiteboard speaking, reading and writing. Can be used in wider range of power supply voltage of 1.8 v to 5.5 v. GTX314L provide the CTRL pin switch can be on the same chip for two parallel operation of chip IDI2C bus.
GTX314L green core chip inside the use of interactive panel board special integrated circuit, high power supply rejection ratio, voltage detection error can reduce the buttons, the application of this feature to ensure in adverse environmental conditions in the chip is still has a high reliability, stronger anti-interference ability accords with national high voltage test, can have high pressure testing, can inject current test, the effect is very obvious.
Touch screen when lit up, is it in the work period, digital touch screen board will continue to launch ultrasonic equipment, when the finger touching the screen, the fingers will stop and absorb some of the ultrasonic wave, the energy attenuation.
