AD9834 DDS Function Signal Generator Module Sine Triangle Square Wave for DIY

AD9834 DDS Function Signal Generator Module Sine Triangle Square Wave for DIY

Specification:    
- Name: AD9834 high speed DDS module
- Size: 50mm X 50mm
- Power: + 5V

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 3 V, the power consumption of only 20 mW, very suitable for power sensitive applications.

AD9834 provides a phase modulation and frequency modulation function. Frequency register 28; clock rate of 75 MHz, can achieve a resolution of 0.28 Hz. Similarly, when the clock rate is 1 MHz, AD9834 can achieve a resolution of 0.004 Hz. 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 40 MHz and is compatible with DSP and microcontroller standards. The device is 2.3 V to 5.5 V power supply. Analog and digital sections are independent, you can use different power supply; for example, AVDD can be 5 V, and DVDD can be 3 V.

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.
