OPB780 - Slotted Switch

Description

The OPB780 programmable color light-to-frequency converter combines configurable silicon photodiodes and a current-tofrequency converter on single monolithic CMOS integrated circuit.

The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance).

Features

  • High-Resolution conversion of Light intensity to Frequency.
  • Communicates Directly with a Microcontroller.
  • Single-Supply Operation (2.7V to 5.5V).
  • Nonlinearity Error Typically 0.2% at 50 kHz.
  • Stable 200 ppm/°C Temperature Coefficient Product Photo Here.

The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The full-scale output frequency can be scaled by one of three preset values via two control input pins.
