AD9835BRUZ

AD9835 is a numerically-controlled oscillator employing a phase accumulator, a COS lookup table, and a 10bit digital to-analogue converter integrated on a single CMOS chip. Modulation capabilities are provided for phase modulation and frequency modulation. Clock rates of upto 50MHz 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 device when it is not in use; the power consumption reduces to 1.75mW. It is widely used in application such as 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 etc.
