TSL235R Light to frequency converter

$3.750
ITEM CODE
32PX604-00084

The TSL235R light-to-frequency converter combines a silicon photodiode and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity. Because it is TTL compatible, the output allows direct interface to a microcontroller or other logic circuitry. The device has been temperature compensated for the ultraviolet-to-visible light range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm.

Features:

  • Communicates directly with a Microcontroller
  • Single-Supply Operation
  • Compact 3-Lead clear plastic package
  • High-resolution conversion of light intensity to frequency with no external components

Specifications:

  • Nonlinearity Error (Typically 0.2% at 100 kHz)
  • Stable 150ppm/°C Temperature Coefficient
  • Supply Voltage 2.7 - 5.5 VDC
  • Operating Temperature range:   −25°C to 70°C
  • Typical current draw 2 mA
  • Output Frequency 200 - 300 kHz

Suggested Applications:

  • Camera exposure
  • Dimming displays
  • Machine vision Key
