Photodiode array with amplifier
This is a Si photodiode array combined with a signal processing IC chip. Improvement in the signal processing IC chip has achieved higher sensitivity compared to the previous products (S11865/S11866 series). The signal processing IC chip is formed by CMOS process and incorporates a timing generator, shift register, charge amplifier array, clamp circuit and hold circuit, making the external circuit configuration simple. A long and narrow image sensor can be configured by arranging multiple arrays in a row. For X-ray detection applications, types with phosphor sheet affixed on the photosensitive area are also available.
