OPB780 Description
The OPB780 programmable color light-to-frequency converter bines 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). The full-scale output frequency can be scaled by one of three preset values via two control input pins.
OPB780 Key Features
- High-Resolution conversion of Light intensity to Frequency
- municates 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
