ams OSRAM TSL2521 Ambient Light Sensor with Flicker Detection provides fast ALS sensing and flicker detection under any glass type. The TSL2520 is designed to fit in the gap between the display screen and the chassis of a smartphone. Sensing flicker in artificial light sources such as LEDs at frequencies up to 7kHz, the TSL2521 provides an image correction input to the phone’s camera. This feature enables the camera to eliminate banding and other flicker-generated artifacts that can distort captured images and videos. The accuracy and high sensitivity of this device, measuring ambient light levels down to just 1mlux, support responsive display brightness management and help improve camera image quality.
The TSL2521 features four photodiodes for visible light sensing and two infrared photodiodes, a combination that allows for the rejection of IR interference and produces very accurate measurements of ambient light intensity (lux).
The ams OSRAM TSL2521 Ambient Light Sensor with Flicker Detection is offered in a compact, low-profile 2.0mm x 1.0mm x 0.5mm optical QFN package ideal for wearable and smartphone applications.
