V2000
Ambient Light Sensor and Proximity Sensor with I2C interface
1. OVERVIEW
Description
The V2000 is an integrated ambient and infrared light to digital converter with 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 V2000 incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be close-to human eye. The V2000 is suitable for detecting a wide range of light intensity environment.
For proximity sensing, the V2000 also incorporates a photodiode, timing controller and ADC in the same chip. The spectral response of V2000 is optimized for wavelength 940nm infrared light. The V2000 provides programmable current setting to drive IR LED and employs a noise cancellation scheme to highly reject unwanted ambient IR noise. The V2000 has excellent temperature compensation, robust on-chip refresh rate setting without external components. Software shutdown mode control is provided for power saving application. The V2000 operating voltage range is 1.7V to 3.0V.
