1Pcs AD9834 DDS Signal Generator Module Sine/Triangle/Square

Description::
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.
