Description
The TSL1401R−LF 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.
