Features: _x000D_ 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. _x000D_ 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. _x000D_ 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. _x000D_ 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. _x000D_ 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. _x000D_ _x000D_ Specifications: _x000D_ Narrow-band SFDR: >72dB _x000D_ Power Supply: 2.3 V~5.5 V _x000D_ Output Frequency: Up to 37.5MHz _x000D_ Output Wave: Sine wave output/triangle wave output _x000D_ Comparator: On-chip comparators _x000D_ Interface: Three-wire Serial Peripheral Interface _x000D_ Extended Temperature Range: -40 to +105 _x000D_ Power Saving Options: Yes _x000D_ Power Consumption: 20mW (when 3V) _x000D_ Size: 5.8 x 6cm/2.28 x 2.36inch _x000D_ Weight: 13g_x000D_ _x000D_ _x000D_ _x000D_ Applications:_x000D_ 1.Frequency stimulus/waveform generation_x000D_ 2.Frequency phase tuning and modulation_x000D_ 3.Low power RF/communications systems_x000D_ 4.Liquid and gas flow measurement_x000D_ 5.Sensory applications: proximity, motion, and defect detection_x000D_ 6.Test and medical equipment_x000D_ _x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1 x Signal Generator _x000D_
