TSL2541

TSL254 : The TSL253 and TSL254 are light-to-voltage optical converters, each combining a 1-mm-square photodiode and a transimpedance amplifier (feedback resistor = 16 MΩ, and 1 MΩ respectively) on a single monolithic IC. Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. These devices use silicon-gate CMOS technology that provides improved amplifier offset-voltage stability and low power consumption.

TSL2540 : The TSL2540 is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output capable of direct I²C interface. The ALS sensor features 2 output channels, a visible channel and an IR channel. The visible channel has a photodiode with a UV and IR blocking filter whereas the IR channel has a photodiode with an IR pass filter. Each channel has a dedicated data converter producing a 16-bit output. This architecture allows applications to accurately measure ambient light which enables devices to calculate illuminance to control a display backlight.
