Photodiode arrays with amplifier
S8865-64G/-128G/-256G, S8866-64G-02/-128G-02
Gain selection terminal voltage setting
Vdd: High gain (Cf=0.5 pF) GND: Low gain (Cf=1 pF)
Setting for each readout method
S8866-64G/-128G, S8866-64G-02/-128G-02
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.
Setting
Readout method
A All stages of parallel readout, serial readout at 1st sensor
B Serial readout at 2nd and later sensors
