Datasheet

Intersil Corporation has announced a light-to-digital sensor, the ISL29020. It delivers unmatched performance by combining low-light sensitivity (<0.015 lux), wide dynamic range, best-in-class spectral response as well as best-in-class IR and UV rejection. The ISL29020 is also leads the industry in power efficiency among light-to-digital sensors, using <65 microamps max operating current.

The ISL29020’s I2C output and interface provides both ease-of-use and enhanced functionality. The digital output is a very simple code directly proportional to lux and requires no complex algorithms.

The ISL29020 also has four selectable ranges of light sensitivity, with sensitivity as low as 0.015 lux to as high as 64,000 lux enabling accurate light sensing in low-light conditions as well as direct sunlight. The ISL29020’s low-light sensitivity, combined with the device’s tiny, translucent six-lead ODFN package, allows the sensor to be embedded in applications behind screens of tinted glass and some fabrics and still perform effectively.

In addition to being the industry’s most power efficient light-to-digital sensor, the ISL29020 also features a 0.5 microamps shutdown current and features software and automatic shutdown.

The ISL29020 is an ideal ambient light sensing solution for smart phones, GPS devices, LCD TVs, portable computing devices and automotive infotainment and display applications.
