TSL2561FN
Light-to-digital Converter, I2C, DFN6, TAOS, RoHS


The TSL2561 is a light-to-digital converter that transforms light intensity to a digital signal output capable of direct I2C (TSL2561) 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. This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. The TSL2561 device supports a traditional level style interrupt that remains asserted until the firmware clears it.

Features:

  • Approximates Human Eye Response
  • Programmable Interrupt Function with User-Defined Upper and Lower Threshold Settings
  • 16-Bit Digital Output: I2C Fast-Mode @ 400 kHz (TSL2561)
  • Programmable Analog Gain and Integration Time Supporting 1,000,000-to-1 Dynamic Range
  • Automatically Rejects 50/60-Hz Lighting Ripple
  • Low Active Power (0.75 mW Typical) with Power Down Mode
  • RoHS Compliant
