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).

• Working voltage: 2.7 ~ 36V

• Working temperature: 0°C～70°C

• Photodiode light irradiation area: 5.2mm2

• Photocurrent: 0.45A/W (λ = 650nm)

• Output voltage ratio: 0.45V/uW

• Analog voltage output range: Vs-1.15

• Bandwidth: 14KHz

• Static power consumption: 120uA

• Pin Function
  

• • 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 1MΩ feedback resistor input

  • OUT: Amplifier output

  • COM: Internal photodiode positive, generally connected to GND

  • Note: The module does not solder the CEXT external capacitor and the REXT external resistor, leaving the pad for easy extension.
