AD9834 is a 75 MHz, low power DDS device capable of producing high performance sine and triangular outputs. Also integrates on-chip comparator, support the generation of square wave for clock generation. When the supply voltage is 3V, the power consumption of only 20mW, 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 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 -controller standards. The device is 2.3V to 5.5V power supply. Analog and digital sections are , 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 , liquid and air flow measurement, sensor applications, , motion and defect detection, testing and equipment.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: -40Celsius to +105CelsiusPower Saving : YesPower Consumption: 20mW (when 3V)Size: 5.8 x 6cm/2.28 x 2.36inchWeight: 13gColour:blackMaterial:plasticPackage Contents:1 x Signal Generator Module SineOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
