description
The TSL1401 linear sensor array consists of a 128 × 1 array of photodiodes, associated charge amplifier
circuitry, and a pixel data-hold function that provides simultaneous-integration start and stop times for all pixels.
The pixels measure 63.5 µm (H) by 55 µm (W) with 63.5-µm center-to-center spacing and 8.5-µm spacing
between pixels. Operation is simplified by internal control logic that requires only a serial-input (SI) signal and
a clock.
