Photodiode arrays

Two photodiode arrays combine a silicon photodiode and signal-processing circuit. The S6493 has a long sensitive area that can be configured into multiple arrays. It is available with 0.88-mm pitch and 64 channels or 0.4-mm pitch and 128 channels, and a phosphor screen type for x-ray detection is also available. The S6494 is available with a 1.6-mm pitch and 64 channels or a 0.8-mm pitch and 128 channels. The signal-processing circuit includes a shift register, clam¥circuit, hold circuit, an
