  • Serial Loading
  • See data sheet for additional features

Product Details

The AD9832 is a numerically controlled oscillator employing a phase accumulator, a sine look-up table, and a 10-bit digital-to-analog converter (DAC) integrated on a single CMOS chip. Modulation capabilities are provided for phase modulation and frequency modulation.

Clock rates up to 25 MHz are supported. Frequency accuracy can be controlled to one part in 4 billion. Modulation is effected by loading registers through the serial interface.

A power-down bit allows the user to power down the AD9832 when it is not in use, the power consumption being reduced to 5 mW (5 V) or 3 mW (3 V). The part is available in a 16-lead TSSOP package.

Applications

  • Frequency stimulus/waveform generation
  • Frequency phase tuning and modulation
  • Low power RF/communications systems
  • Liquid and gas flow measurement
  • Sensory applications: proximity, motion, and defect detection
  • Test and medical equipment

Design Tools

ADIsimDDS (Direct Digital Synthesis)

ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. ADIsimDDS calculates the required FTW, given the reference clock frequency and desired output frequency. This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
