All typical values are at Ta = 25 °C unless otherwise noted.
* Maximum CCM gain is not guaranteed.
** The values in the table are quoted using CDS = Correlated Double Sampling. CDS is a signal
processing technique that improves performance by minimizing undesirable effects of reset noise.
Notes :
3. Excess Noise Factor “F” is defined as the ratio of noise sigma after multiplication divided by M
times the noise sigma before multiplication where M is the charge multiplication gain.
4. Dynamic Range is –20 times the logarithm of the noise sigma divided by the saturation–output
signal amplitude
5. Charge conversion factor is defined as the ratio of output signal to input number of electrons.
6. Signal-response delay time is the time between the falling edge of the SRG1 pulse and the output-
signal valid state.
7. Charge transfer efficiency is one minus the charge loss per transfer in the CCD register. The test is
performed in the dark using either electrical or optical input.
