General Description
The MLX90255xx linear sensor array consists of a 128 x 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 200µm (H) by 66 µm (W) and there is 8 µm spacing between pixels. Operation is simplified by internal control logic that requires only a Serial Input (SI) pulse and a clock signal.
