STK3338-V Datasheet | Sensortek

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 STK3338-V is suitable for detecting a wide range of light intensity environment. For proximity sensing, the STK3338-V also incorporates a photodiode, timing controller and ADC in the same chip. The spectral response of STK3338-V is optimized for wavelength 940nm infrared light. The STK3338-V provides programmable current setting to drive VCSEL and employs a noise cancellation scheme to highly reject unwanted ambient noise. The STK3338-V has excellent temperature pensation, robust on-chip refresh rate setting without external ponents. Software shutdown mode control is provided for power saving application. The STK3338-V operating voltage range is 1.7V to 3.0V. High ambient light suppression 940nm VCSEL for STK3338-V.
