General Description

The LM9832 is a complete USB image scanner system on a single IC.

The LM9832 provides all the functions (image sensor control, illumination control, analog front end, pixel processing function image data buffer/DRAM controller, microstepping motor controller, and USB interface) necessary to create a high performance color scanner.

The LM9832 scans images in 42 bit color/14 bit gray, and has output data formats for 42 and 24 bit color/14 and 8 bit gray.

Key Features

  • 14 bit ADC digitizes at up to 6Mpixels/s (2M RGB pixels/sec).
  • Digital Pixel Processing provides 1200, 800, 600, 400, 300, 200, 150, and 100dpi horizontal resolution from a 1200dpi sensor and 600, 400, 300, 200, 150, 100, 75, and 50dpi horizontal resolution from a 600dpi sensor.
  • Provides 50-2400dpi vertical resolution in 1 dpi increments.
  • Pixel rate error correction for gain (shading) and offset errors.
  • Supports 4 or 16Mbit external DRAMs.
