The STK3335-X is an integrated ambient light sensor and proximity sensor with a built-in IR LED and I2C interface. It offers robust backlight/display brightness control through ambient light sensing and proximity estimation via infrared sensing, featuring an interrupt function. The device boasts a spectral response close to the human eye for ambient light and is optimized for 940nm infrared light for proximity sensing. It includes programmable IR LED current, noise cancellation for ambient IR noise rejection, excellent temperature compensation, and on-chip refresh rate setting. A software shutdown mode is available for power saving. The STK3335-X operates within a voltage range of 1.7V to 2.0V.
