Description
The TSL1401CS−LF 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 55.5 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.
