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.
