ams OSRAM TSL2540 Ambient Light Sensor Converters

ams OSRAM TSL2540 Ambient Light Sensor Light-to-Digital Converters transform light intensity into a digital signal output capable of direct I2C interface. The high-sensitivity sensor features two output channels, a visible channel, and an infrared channel. The converter's visible channel has a photodiode with ultraviolet and IR-blocking filters. The sensor's channels have a dedicated data converter that produces a 16-bit output, allowing applications to accurately measure ambient light. This feature enables devices to calculate illuminance to control a display backlight.
