GT304L Capacitive 4-Key Touch Chip-Super Strong Anti-Interference, Low Power Consumption

GT304L is a 4 -channel capacitor touch chip launched by GreenChip (green core), South Korea, which provides 4 touch input ports and 4 direct output ports;The advantages of reliability, fast wake -up mode; provide users with more flexibility and multifunctionality.

Product Description:

GT304L touch chip, its working power supply voltage range:2.5V～5.0V;unique嵌入式GreenTouch3TM engine; provides two forms of packaging: SOP14L, QFN16L,Support 1: 1 DC output mode and I2C interface mode;supply4 LEDsDrives and32 -order light控制器; OUT [1: 4] Port can be used for PWM output, for LED lighting control, and does not require additional material costs to control LEDs.

Its super -strong anti -interference ability can maintain a stable working state in a complex electromagnetic environment, not affected by external interference, and ensure the stability and reliability of the equipment; with high penetration power, you can achieve precise touch control on the surface of different materials., Bring users a more convenient and smooth operation experience.

Unique embedded GreenTouch engine algorithm, simulation compensation电路; Embedded digital noise filter has intelligent super high sensitivity calibration; has strong anti -interference ability to electromagnetic compatibility, electromagnetic interference, temperature and humidity changes, voltage interference, temperature drift, humidity drift, etc.Caused by mistake.
