ML8511 - SOI-based UV-sensor IC with voltage output
Description
The ML851 1 is the world´s first thin-film SOI (¹) UV-sensor with an integrated OpAmp - this a major breakthrough compared to conventional UV-sensors based on compound semiconductors. Now available in volume, including chip calibrationfor highest accuracy.
Enabling an analog voltage output function proportional to UV light intensity (UV-A and UV-B) on a single chip, the ML8511 does not require an optical cut filter. This enables manufacturers to develop compact and highly mobile UV devices at low cost.
In addition to conventional applications such as accessory-type devices to measure the amount of UV in daylight, the ML8511 can be used in many home appliance applications.
(¹) SOI: Silicon-on-Insulator
