Product Description
Product Overview
The TSL2540 is a highly sensitive light-to-digital converter that provides a digital signal output with direct IC interface capabilities. It features two output channels: a visible channel with a UV and IR blocking filter, and an IR channel with an IR pass filter. Each channel offers a 16-bit output, enabling accurate ambient light measurement for applications such as calculating illuminance to control display backlights. The device offers programmable gain and integration time, reduced power consumption, and operates on a 1.8V power supply with a 1.8V IC bus.
