Photodiode array with amplifier
S8865 series
Photodiode array combined with signal processing circuit chip
S8865 series is a Si photodiode array combined with a signal processing circuit chip. 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 also be configured by arranging multiple arrays in a row. For X-ray detection applications,
types with fluorescent paper affixed on the active area are also available.
Features
l Large element pitch: 2 types available
S8865-64: 0.8 mm pitch × 64 ch
S8865-128: 0.4 mm pitch × 128 ch
l 5 V power supply operation
l Simultaneous integration by using a charge amplifier
array
l Sequential readout with a shift register
(Data rate: 1 MHz Max.)
l Low dark current due to zero-bias photodiode
operation
l Integrated clamp circuit allows low noise and wide
dynamic range
l Integrated timing generator allows operation at two
different pulse timings
l Types with phosphor screen affixed on the active area are
available for X-ray detection: S8865-64G/S8865-128G
Applications
l Long line sensors
l Line sensors for X-ray detection
