2 / 25 page 1 www.national.com General Description The LM9822 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 LM9822 has a 14 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 • InternalVoltage Reference Generation • TTL/CMOS compatible input/output Key Specifications • Output Data Resolution 14 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 LM9822 3 Channel 42-Bit Color Scanner Analog Front End Connection Diagram LM9822 28 pin SOIC SCLK SDI SEN D2 D0 VD DGND D4 11 12 13 14 15 16 17 18 19 20 1 2 3 4 5 6 7 8 9 10 23 22 21 24 25 26 27 28 D7 D6 D5 MCLK VA VA VREF- OSB OSG CLMP OSR VREF+ AGND AGND VSMP SDO VREFMID VBANDGAP D3 D1 May 1999 N ©1999 National Semiconductor Corporation TRI-STATE® is a registered trademark of National Semiconductor Corporation.
