In May 2008, Intersil, recently announced the most easily used optical to digital sensor in the industry. When applied to mobile phones, computers and consumer electronics, the sensor can extend the life of the battery and supply enhanced function and performance. Both the new ISL29010 and ISL29013 are highly accurate sensors that measure and digitize the value of the ambient light, and then allow access to this information through a standard I2C interface.
By adjusting the various applications automatically with different light conditions, a simple method for improving efficiency and functionality is supplied to end products. Its performance advantage includes extending battery life from the keyboard, dimming the display brightness of the mobile device and the performance of the LCD panel, digital photo frame, and digital cameras. The spectral reaction of these devices is attenuated with unnecessary infrared radiation, even in the extremely low light conditions, accurate light measurement can also be supplied.
This is achieved by integrating a complete light to digital solution, including specially tuned photodiodes to remove all unnealed infrared noise, a 15-bit built-in symbol simulation digital conversion to low light sensitivity and automatic elimination noise Be aware of. The features of ISL29010 and ISL29013 also include gain choices, ensuring that designers can choose dynamic range and low light sensitivity, so that the most perfect match is matched with their application needs. This functionality implemented by software, that is, between the low light sensitivity and the wider dynamic range, ensures the highest performance and unparalleled flexibility.
The device has a running voltage of 2.5V to 3V and only supplies 250 micro-hustle currents, which is lower than any existing light to digital sensor chip. In addition, the power-off mode can be controlled by the software through the I2C interface, thereby reducing power consumption to less than 1 microamily.
Both models have a built-in symbol ADC, and can convert small current signals in the case of AC cycle noise. The ADC can supply a flexible integrated mode and conversion time to the user through internal or external mode, while suppressing the flash of 50 Hz and 60 Hz caused by the exogenous source. Users can adjust the Lux range of light intensity to optimize count / illuminance ratio.
As an additional function, ISL29013 includes an interrupt pin, user can set a threshold to detect a specific high or low light threshold. ISL29010 includes an address selection pin, so two light sensors can be used on the same I2C bus. Pricing and availability ISL29010 and ISL29013 now use 6-pin ODFN package (2mmx2.
1mm) unit price of 1000 tablets at $ 1.2. .
