description
The TSL401 linear sensor array consists of a 128 × 1 array of photodiodes and associated charge amplifier
circuitry. The pixels measure 63.5 µm (H) × 50 µm (W) with 63.5-µm center-to-center spacing and 13.5 µm
between pixels. Operation is simplified by internal logic requiring only a serial input (SI) signal and a clock.
