Product Details
The AD9835 is a numerically-controlled oscillator employing a phase accumulator, a COS lookup table, and a 10-bit digital-to-analog converter integrated on a single CMOS chip. Modulation capabilities are provided for phase modulation and frequency modulation.
Clock rates of up to 50 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 AD9835 when it is not in use, the power consumption reduces to 1.75 mW.
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
