S8865-128G HAMAMATSU [Hamamatsu Corporation], S8865-128G Datasheet - Page 11

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

Vdd: High gain (Cf=0.5 pF) GND: Low gain (Cf=1 pF)
Set to A in the table below in most cases.
To serially read out signals from two or more sensors linearly connected, set the 1st sensor to A and the 2nd or later sensors to B.
The CLK and RESET pulses should be shared with each sensor and the video output terminal of each sensor connected together.
