AD9832BRUZ

AD9832 is a numerically controlled oscillator employing a phase accumulator, a sine look-up table, and a 10-bit digital-to-analogue converter (DAC) integrated on a single CMOS chip. Modulation capabilities are provided for phase modulation and frequency modulation. 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 5mW(5V) or 3mW(3V). Typical application includes 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.
