When we (attempt to) digitalize everything, there are always things left to the human senses – emotion, morality, aesthetics, and aesthesia... Well, there's something we can do about aesthesia with analog to digital conversion (ADC) technology.
Light sensor is a perfect example of how ADC technology has been adopted for people to access and utilize the digitalized world. Being at the vanguard of technology innovation, uPI provides the most advanced and extensive analog digital conversion (ADC) solutions by incorporating the advantages of silicon design, foundry-based process fine-tuning and manufacturing capacity. Highly efficient, designer-friendly, varied and with a cladding filter-free technology, these solutions are part of the uS family of products that include: a full range of ambient light sensors (ALS), proximity detectors, multi-functional sensors, and UV sensors.
Cladding Filter-Free: Closest Spectrum to Human-Eye Sensitivity
Unlike traditional wafer-coating methodology, the uS series of light sensors incorporate photon sensor, amplifiers and analog/digital circuits into a single chip by CMOS process. Such innovative cladding filter-free technology provides not only lower production time and cost, but also provides the closest spectrum to human-eye sensitivity in the market!
Variety of Choices
uPI's uS510x and uS515x series products, in both analog (current / voltage) and digital I2C output types, are designed to dynamically adjust the brightness of LED/LCD display to best suit human-eye visibility and ambient light.
uS513x and uS518x series products showcase multiple combination among analog/digital output ambient light sensors, proximity sensors, and IR LED drivers. The compact all-in-one solution fulfills the complex need of ambient light sensing and proximity detection for smart phones, digital cameras or monitors/laptops with presence-detecting features.

| Ambient Light | Proximity | ALS+PS+LED | ALS+PS+LED | UV |
| Analog | uS510x series | uS511x series | uS513x series | uS512x | uS514x series |
| Digital I2C | uS515x series | uS516x series | uS518x series | uS517x | uS519x series |
High Efficiency and Designer-friendly
The built-in shut-down function and low shutdown/supply current effectively optimizes the efficiency, which benefits the battery-powered devices. Selectable current/voltage output gain (uS510x), I2C programmable shutdown control (uS516x) and adjustable ambient light sensitivity (uS510x, uS515x, uS513x, uS518x) provides designers best flexibility in designs.
