TSL2561 datasheet



The TSL2560 and TSL2561 are light-to-digital converters that transform light intensity to a digital
signal output capable of direct I2C (TSL2561) or SMBus (TSL2560) interface. Each device combines
one broadband photodiode (visible plus infrared) and one infrared-responding photodiode
on a single CMOS integrated circuit capable of providing a near-photopic response over an
effective 20-bit dynamic range (16-bit resolution).

Two integrating ADCs convert the photodiode currents to a digital output that represents the
irradiance measured on each channel.


1. Approximates Human Eye Response to Control Display Backlight and Keyboard Illumination
2. Precisely Measures Illuminance in Diverse Lighting Conditions Providing Exposure
Control in Cameras
3. Programmable Interrupt Function with User-Defined Upper and Lower Threshold Settings
4. 16-Bit Digital Output with SMBus (TSL2560) or I2C (TSL2561) Fast-Mode at 400 KHz
5. Programmable Analog Gain and Integration Time Supporting 1,000,000-to-1 Dynamic Range
6. Available in Ultra-Small 1.25 mm1.75 mm Chipscale Package
7. Automatically Rejects 50/60-Hz Lighting Ripple
8. Low Active Power (0.75 mW Typical) with Power Down Mode
9. RoHS Compliant
