Description
The MLX90255BA 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). Operation is simplified by internal control logic that requires only a serial-input (SI) signal and a clock.
