16-Lead TSSOP The AD9835 is a numerically-controlled oscillator employing
a phase accumulator, a COS lookup table, and a 10-bit digitalto-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. APPLICATIONS This part is available in a 16-lead TSSOP package. 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 …
