An optical IC light detector that consists of a light detecting element that is sensitive to the near infrared portion of the spectrum, together with associated signal processing circuitry, all integrated onto a single chip. The device employs a light modulating system which makes the device impervious to disturbance from external lights.

• Spectral sensitivity range approx 700nm to 1150nm (near infrared)
• Wide operating supply voltage range 4.5V to 16V
• 2pd Differential type
• Through-hole type
• Offset leads 4-pin package
• Sharp IS471FE type
