Description
The TSL1410R linear sensor array consists of two
sections of 640 photodiodes, each with
associated charge amplifier circuitry, aligned to
form a contiguous 1280
脳
1 pixel array. The device
incorporates a pixel data-hold function that
provides simultaneous-integration start and stop
times for all pixels. The pixels measure 63.5
碌m
by
55.5
碌m
with 63.5-碌m center-to-center spacing
and 8-碌m spacing between pixels. Operation is
simplified by internal logic that requires only a
serial-input (SI) pulse and a clock.
