Photodiode array combined with signal processing IC for X-ray detection

 

The S8865-64G is a photodiode array with an amplifier and a phosphor sheet attached to the photosensitive area for X-ray detection. The signal processing circuit 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, narrow image sensor can be configured by arranging multiple arrays in a row.
As the dedicated driver circuit, the C9118 series (sold separately) is provided.

 

Features
-Large element pitch: 0.8 mm pitch × 64 ch
-5 V power supply operation
-Simultaneous integration by using a charge amplifier array
-Sequential readout with a shift register (Data rate: 500 kHz max.)
-Low dark current due to zero-bias photodiode operation
-Integrated clamp circuit allows low noise and wide dynamic range
-Integrated timing generator allows operation at two different pulse timings
-Detectable energy range: 30 k to 100 keV
