• Manufacturer Part Number: S8865-128G
• Description: Photodiode array combined with signal processing IC for X-ray detection
• Manufacturer: HAMAMATSU [Hamamatsu Corporation]

Signals of channels 1 through 126 are output from CMOS1, while signals of channels 129 through 256 are output from CMOS2. The follow-
ing two readout methods are available.
(1) Serial readout method
CMOS1 and CMOS2 are connected in serial and the signals of channels 1 through 256 are sequentially read out from one output line. Set
CMOS1 as in “A” in the table below, and set CMOS2 as in “B”. CMOS1 and CMOS2 should be connected to the same CLK and RESET lines,
and their video output terminals to one line.
(2) Parallel readout method
128 channel signals are output in parallel respectively from the output lines of CMOS1 and CMOS2. Set both CMOS1 and CMOS2 as in “A” in
the table below.
[Figure 2] Connection
Check that pulse signals meet the required pulse conditions before supplying them to the input terminals.
Video output should be ampli ed by an operational ampli er that is connected close to the sensor.
