General Description

The TSL1401CL linear sensor array consists of an 128 × 1 array of photodiodes, associated charge amplifier circuitry, and an internal pixel data-hold function that provides simultaneous integration start and stop times for all pixels. The array is made up of 128 pixels, each of which has a photo-sensitive area of 3524.3 square micrometers. There is 8-μm spacing between pixels. Operation is simplified by internal control logic that require only a serial-input (SI) signal and a clock.

This product suits for the following applications:

  • Printer edge detection
  • Scanners
  • Optical character recognition
  • Position sensing
