Ordering Information
FAQ
The above graph is measured on an IBIS4-1300 under nominal
operation, using breadboard. This particular sensor has about
100 "bad pixels" at RT.
Average offset (=dark signal) and RMS (=FPN of dark signal) are
measured versus temperature. Offset is referred to the "short
tint" offset at 20 C. Integration time was 160 ms (= "long tint").
Y-axis is the output signal (100% = ADC range)
Useful Range of "Double Slope"
Which total dynamic range can reasonably be obtained with the
dual slope feature of the IBIS4-1300?
Assuming that the "regular" S/N is 2000:1, and that one can put
the knee point halfway the voltage range, the each piecewise
linear halve has 1000:1 S/N. If the ratio between slopes is a, then
the total dynamic range becomes (1000+a*1000):1.

Example, is a=10, then the total dynamic range becomes
11000:1.
In practice, acceptable images are obtained with a up to 10.
Larger a's are useable, but near the knee, contrast artifacts
become annoying.
Skipping Rows or Columns
Although these modes are not described in the datasheets, it is
possible to skip rows or columns by simply applying additional
CLK_YR + CLR_YL, or CLK_X pulses. The maximum clock
frequency is not documented. But it is probable that one can
reach at least 10 MHz in Y and 40 MHz in X.
