Maxim Integrated Products has entered the optical sensor market with the launch of a fully integrated digital ambient-light sensor (ALS) with a unique adaptive gain block. The MAX9635 integrates two photodiodes, an analog-to-digital converter (ADC), and all necessary digital functionality in a 2 x 2-mm package. The MAX9635 is well-suited for tablet and notebook PCs, smart phones, TVs, digital lighting-management systems, and light-intensity monitoring applications.
Designed using the company’s proprietary BiCMOS technology, Maxim said the MAX9635 consumes 100x less power than the nearest competitive product, which significantly extends battery life. The device also offers an industry-best 4,000,000 to 1 dynamic range to ensure ultra-precise lux readings in all ambient-light conditions, according to the Sunnyvale, Calif.-based company.
The MAX9635 is housed in an optically transparent, lead-free, 2 x 2 x 0.6-mm, 6-pin UTDFN-Opto-EP package. The extended operating temperature range is -40 deg. C to +85 deg. C.
