Notes:
1 _{Charge pump off, temp sensor off, video amplifier BW=LOW_BW, VIDEO_GBW_SEL_REG=0x0 (minimum video amplifier bias current,}
Read Clock 1MHz).
2 _{The linearity is defined as the maximum deviation of the pixel responses between 10% and 80% FW}4 _{from the straight line between 10%}
and 80% FW⁴. Pixels with high dark current excluded.
3 _{Pixel 3 .. 1020}
4 _{FW corresponds to 2V swing at the output in differential mode.}
