Photodiode arrays with ampliﬁer

S8865-64G/-128G/-256G

S8866-64G-02/-128G-02

Photodiode array combined with signal

processing IC for X-ray detection

The S8866-64G-02/-128G-02 are photodiode arrays 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. (Not compatible with the S8865-256G and

S8866-64G-02.)

Features

Applications

Large element pitch: 5 types available

S8865-64G: 0.8 mm pitch × 64 ch

S8865-128G: 0.4 mm pitch × 128 ch

S8865-256G: 0.2 mm pitch × 256 ch

S8866-64G-02: 1.6 mm pitch × 64 ch

S8866-128G-02: 0.8 mm pitch × 128 ch

Line sensors for X-ray detection

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
