製品名 概要 特徴
Photo Diode IC  for Optoelectronic Switch
A photo diode IC that outputs the presence or absence of an incident light signal and the amount of light as a voltage waveform.
Performance is improved compared to other companies' products.
  • 5X faster

  • More than double the S/N

  • No external shield required

  • Frequency 1MHz

  • High linearity

  • low noise

  • Resistant to external

     electromagnetic noise

  • Light-receiving surface

     (0.7mm x 0.7mm x 2 pieces)

Short distance optical wireless IC
  • High speed photo IC
  • A photo IC that outputs incident light as a voltage waveform.
  • Our original photo ditector makes low capacitance and low noise possible.
  • Contains a coupling capaciter for cutting DC and therefore removes noice interference.
