Description: The AD9834 is a 75 MHz, low-power direct digital frequency synthesis (DDS), can produce high-performance sine wave and triangle wave output. It also has an on-chip comparator can be used to generate the square wave clock. The device is only 20 mW at 3 V power consumption is ideal for power sensitive applications.
Also provides the phase modulation and frequency modulation capability. The frequency register 28 clock rate of 75 MHz, 0.28 Hz resolution. Similarly, when the clock rate of 1 MHz can be achieved tuning resolution of 0.004 Hz. Loading registers through the serial interface, the use of the software or FSELECT pin and PSELECT pin switching register, frequency and phase modulation can be realized.
AD9834 via a three-wire serial interface to write data. The serial interface can work up to 40 MHz clock rate, and is compatible with DSP and microcontroller standards.
The device is 2.3 V to 5.5 V power supply. Separate analog and digital sections, you can use a different pow
