General Description
The LM9823 is a high performance Analog Front End (AFE) for
image sensor processing systems. It performs all the analog and
mixed signal functions (correlated double sampling, color spe-
cific gain and offset correction, and analog to digital conversion)
necessary to digitize the output of a wide variety of CIS and
CCD sensors. The LM9823 has a 16 bit 6MHz ADC.
Features
• 6 million pixels/s conversion rate
• Digitally programmed gain and offset for red, green and blue
color balancing
• Correlated Double Sampling for lowest noise from CCD
sensors
• Compatible with CCD and CIS type image sensors
• Internal Voltage Reference Generation
• TTL/CMOS compatible input/output
Key Specifications
• Output Data Resolution
16 Bits
• Pixel Conversion Rate
6MHz
• Analog Supply Voltage
5V±5%
• I/O Supply Voltage
3.3V±10% or 5V±5%
• Power Dissipation (typical)
375mW
Applications
• Color Flatbed Document Scanners
• Color Sheetfed Scanners
• Multifunction Imaging Products
• Digital Copiers
• General Purpose Linear Array Imaging
