Features:

AD9834

is a 75 MHz, low power DDS device capable of producing high performance

sine and triangular outputs. Also integrates its on-chip comparator,

support the generation of square wave for clock generation. When the

supply voltage is 3V, the power consumption of only 20mW, very suitable

for power sensitive applications.

AD9834

provides a phase modulation and frequency modulation function.

Frequency register 28bit; clock rate of 75MHz, can achieve a resolution

of 0.28 Hz. Similarly, when the clock rate is 1 MHz, AD9834 can achieve a

resolution of 0.004Hz. Affect the frequency and phase modulation method

is through the serial interface to load the register, then register by

software or FSELECT / PSELECT pin switches Device.

AD9834

via a three-wire serial interface to write data. The serial interface

that operates at clock rates up to 40MHz and is compatible with digital

signal processing and micro-controller standards. The device is 2.3V to

5.5V power supply. Analog and digital sections are independent, you can

use different power supply; for example, AVDD can be 5V, and DVDD can be

3V.

AD9834

has a control pin Sleep (SLEEP), to support power-down mode control

from the outside. No part of the device may shut off to minimize power

consumption. For example, when generating a clock output can be turned

off DAC. The device uses a 20-pin TSSOP package.

Used

for frequency excitation/waveform generation, frequency phase tuning

and modulation, low-power RF/communication systems, liquid and air flow

measurement, sensor applications, proximity, motion and defect

detection, testing and medical equipment.
