Description
The TSLW1401R 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.
