Product Description
Product Overview
The STK2236-X is an integrated ambient light sensor with an I2C interface, designed for robust backlight and display brightness control. It features a photodiode, timing controller, and ADC on a single chip, offering excellent spectral response close to human eye sensitivity and suppressing IR. This device is suitable for a wide range of light intensity environments, with excellent temperature compensation and on-chip refresh rate setting. A software shutdown mode is available for power saving. The STK2236-X operates from 1.7V to 3.3V.
