LM9810/LM9820
10/12-Bit Image Sensor Processor Analog Front End
General Description
The LM9810 and LM9820 are high performance Analog
Front Ends (AFEs) for image sensor processing systems.
The LM9810/20 performs all the analog and mixed signal
functions (correlated double sampling, color specific gain
and offset correction, and analog to digital conversion) nec-
essary to digitize the output of a wide variety of CIS and CCD
sensors. The LM9810 has a 10-bit 6 MHz ADC, and the
LM9820 has a 12-bit 6 MHz ADC. The LM9810 and LM9820
are pin-for-pin and functionally compatible.
