Digital output type ambient light sensor IC is composed of photodiodes, current-voltage converter circuit, A / D converter, control logic circuits, interface circuits and etc. It connects with I²C Bus in an equipment.
Feature
- I²C bus Interface ( f / s Mode Support, Slave address "0101001". )
- There are two outputs that peaks of a spectrum response are in visible light (Type0) and in infrared light (Type1).
- Illuminance to Digital Converter
- Very wide range and High resolution. ( 0.008 - 65535 lx )
- Low Current by power down function
- 50Hz / 60Hz light noise reject-function
- Correspond to 1.8V logic input interface
- Light source dependency is little by calculating with Type0 and Type1. ( ex. Incandescent Lamp. Fluorescent Lamp. Halogen Lamp. White LED. Sun Light )
- Interrupt function is available.
- Adjustable measurement result for influence of optical window. (It is possible to detect min. 0.001 lx, max. 100000 lx by using this function.)
- Small measurement variation (+/- 15%)
- Built in power on reset circuit.
