Description

The OPT101 is an illuminance photosensor that integrates a photodiode and a specially optimized op amp. The transparent package allows the photodiode to have a larger sensing surface with higher sensitivity and a wide spectral response range (infrared to visible light 300nm-1000nm).

  • Output voltage ratio: 0.45V/uW
  • Analog voltage output range: Vs一1.15
  • Bandwidth: 14KHz
  • Static power consumption: 120uA

 

Pin Functions

VCC: power supply positive pin
-V: negative supply
-IN: the inverting input of the internal op amp and the negative of the internal photodiode,
Do not connect or apply feedback that is abandoned in the operation
1M: Internal 1M feedback resistor input
OUT: Amplifier output
COM: Internal photodiode positive, generally connected to GND
