1. OVERVIEW
Description
The STK3338-V is an integrated ambient and infrared light to digital converter with a built-in 940nm VCSEL (Vertical-Cavity Surface-Emitting Laser) diode and I2C interface. This device provides not only ambient light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation featured with interrupt function.
For ambient light sensing, the STK3338-V incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be close-to human eye. The...
