TSL2561CS Overview

Part: TSL2560 / TSL2561 — ams AG

Type: Light-to-Digital Converter

Description: The TSL2560 and TSL2561 are light-to-digital converters that transform light intensity to a digital signal output, providing a near-photopic response over an effective 20-bit dynamic range with 16-bit resolution, and featuring programmable gain and integration time.

Operating Conditions:

  • Supply voltage: 2.7–3.6 V
  • Operating temperature: -30 to 70 °C
  • I2C clock frequency: 0–400 kHz (TSL2561)
  • SMBus clock frequency: 10–100 kHz (TSL2560)

Absolute Maximum Ratings:

  • Max supply voltage: 3.8 V
  • Max digital output current: 20 mA
  • Max storage temperature: 85 °C

Key Specs:

  • Supply current (Active): 0.24 mA (Typ)
  • Supply current (Power down): 3.2 μA (Typ)
  • INT, SDA output low voltage (3 mA sink): 0.4 V (Max)
  • INT, SDA output low voltage (6 mA sink): 0.6 V (Max)
  • Leakage current: -5 to 5 μA
  • Conversion time: 12 ms (Min), 100 ms (Typ), 400 ms (Max)
  • Data setup time: 100 ns (Min)
  • Input pin capacitance: 10 pF (Max)

Features:

  • Approximates Human Eye Response
  • Programmable Interrupt Function with User-Defined Upper and Lower Threshold Settings
  • 16-Bit Digital Output with SMBus (TSL2560) at 100 kHz or I2C (TSL2561) Fast-Mode at 400 kHz
  • 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

Applications:

  • Display panels (LCD, OLED, etc.) for extending battery life and optimum viewing
  • Controlling keyboard illumination
  • Exposure control in digital cameras
  • Notebook/tablet PCs, LCD monitors, flat-panel televisions, cell phones
  • Street light control, security lighting, sunlight harvesting, machine vision, automotive instrumentation clusters

Package:

  • Chipscale (CS)
  • TMB-6 (T)
  • Dual Flat No-Lead - 6 (FN)
  • ChipLED-6 (CL)
