Overview
Data Sheet 50 MHz Direct Digital Synthesizer, Waveform Generator AD9835 FEATURES 5 V power supply 50 MHz speed On-chip COS lookup table On-chip, 10-bit DAC Serial loading Power-down option Temperature range: −40°C to +85°C 200 mW power consumption 16-Lead TSSOP 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 GENERAL DESCRIPTION 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.
This part is available in a 16-lead TSSOP package.
