AD9833 Module Triangular Sine Wave Signal Source Square Wave Generator DDS Signal Generator Data Sending Program -72351

AD9833 DDS Signal Generator Module DC 0-12.5MHZ SPI Square Triangle Sine Wave Serial Interface Programmable Frequency and Phase GY-AD9833

The AD9833 is a low power, programmable waveform generator that produces sine, triangle, and square wave outputs. Waveform generators are required for various types of detection, signal excitation, and time domain reflectometry (TDR) applications. The output frequency and phase can be programmed via software for easy adjustment. No external components are required. The frequency register is 28 bits: a resolution of 0.1 Hz can be achieved at a clock rate of 25 MHz, and a resolution of 0.004 Hz at a clock rate of 1 MHz. The AD9833 writes data through a three-wire serial interface. The serial interface operates at clock rates up to 40 MHz and is compatible with DSP and microcontroller standards. The device operates from a 2.3 V to 5.5 V supply. The AD9833 has a power saving function. This feature allows power to be minimized by shutting down unused parts of the device. For example, the DAC can be turned off when the clock output is generated.
