Description
The TSL1401R linear sensor array consists of a 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 pixels measure 63.5 µm (H) by 55.5 µm (W) with 63.5-µm center-to-center spacing and 8-µm
spacing between pixels. Operation is simplified by internal control logic that requires only a serial-input (SI)
signal and a clock.
