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

Features:AD9834is a 75 MHz, low power DDS device capable of producing high performancesine 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.AD9834provides 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 aresolution of 0.004Hz. Affect the frequency and phase modulation methodis through the serial interface to load the register, then register by software or FSELECT / PSELECT pin switches Device.AD9834via 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 be3V. AD9834has 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.Usedfor 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.Specifications:Narrow-band SFDR: >72dBPower Supply: 2.3 V~5.5 VOutput Frequency: Up to 37.5MHzOutput Wave: Sine wave output/triangle wave outputComparator: On-chip comparatorsInterface: Three-wire Serial Peripheral InterfaceExtended Temperature Range: -40℃to +105℃Power Saving Options: YesPower Consumption: 20mW (when 3V)Size: 5.8 x 6cm/2.28 x 2.36inchWeight: 13gApplications:1.Frequency stimulus/waveform generation2.Frequency phase tuning and modulation3.Low power RF/communications systems4.Liquid and gas flow measurement5.Sensory applications: proximity, motion, and defect detection6.Test and medical equipmentPackage Includes:1 x Signal Generator
