Typical Performance Characteristics

Full Channel DNL and INL

(Divide by 2, Monochrome Mode, 6 MHz Pixel Rate)

Note: The LM9823 provides 16-bit data for high resolution imaging applications. The typical full channel device performance is shown

in the above graphs. In many applications, particularly those where high speed is important, or where lower cost CCD and CIS sensors

are used, the signal source is only accurate to 12 bits. In these applications, only 12-bit of data may be used. 12-bit DNL and INL plots

have also been provided to illustrate the performance of the LM9823 in these applications.
