LM98501 - National Semiconductor

LM98501 10-Bit / 27 MSPS Camera Signal Processor

The LM98501 is a CCD signal processor for electronic cameras. The processor provides a common interface to a number of different image sensors including CCD, CMOS, and CIS. Correlated double sampling reduces kTC noise from the image signal. A fast, temperature stable, 8-bit digitally programmable gain amplifier enables pixel-rate white-balancing. An auxiliar.
