Description
The TSL1412S linear sensor array consists of 2
sections of 768 photodiodes, each with
associated charge amplifier circuitry, aligned to
form a contiguous 1536 × 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 μm by
55.5 μm with 63.5-μm center-to-center spacing
and 8-μm spacing between pixels. Operation is
simplified by internal logic that requires only a
serial-input (SI) pulse and a clock.
