AD9833 Programmable Microprocessors Serial Interface Module Sine Square Wave DDS Signal Generator Module GY-9833

The AD9833 is a low-power, programmable generator capable of producing sinusoidal waveform generators, triangular wave and square wave outputs. Generation is required in various types of waveform detection, implementation, and time domain reflectometer (TDR) applications. The output frequency and phase are programmable software for easy adjustment. No external components are necessary. The frequency register is 28 bits wide: the clock frequency is 25 MHz, enabling a resolution of 0.1Hz; The AD9833 is clocked at 1 MHz and can be tuned to a resolution of 0.004Hz

The AD9833 has a standard serial interface that allows the device to connect directly to different microprocessors. The device uses an external serial clock to write data or information to the control device

The AD9833WBRMZ-REEL model can be controlled to meet the quality and reliability requirements of automotive applications. Please note that car specifications for this model may differ from commercial models; Therefore, designers must carefully read specific parts of this data sheet. Only automotive grade indication products are available for automotive applications. Please contact your local ADI representative account for specific product ordering information and for specific vehicle reliability reports for these models

The AD9833 is written over a serial interface line. The serial interface operates at a clock rate of up to 40 MHz and is standard compatible with DSPS and microcontrollers. The device uses a 2.3V 5.5V power supply

The AD9833 has a power down function (SLEEP). This can turn off unused parts of the device, which minimizes power consumption, for example, the DAC can be turned off while the output clock is being generated
