PRODUCT DETAILS

Description

DDS (Direct Digital Synthesis) Unit is a signal source unit that combines the AD9833 programmable waveform generator with the STM32F0 microcontroller. It utilizes the I2C communication interface with the address 0x31 to control the signal source and output various waveforms.

The AD9833 waveform generator allows for the generation of multiple waveforms, including sine wave, triangle wave, square wave, and sawtooth wave. The signal output amplitude ranges from 0 to 0.6V, providing flexibility in adjusting the output level.

The DDS unit also incorporates the STM32F0 microcontroller, which facilitates the control and configuration of the waveform generator. Through the I2C communication interface, the microcontroller can easily adjust the frequency and phase of the generated signal.

To optimize power consumption, the DDS unit supports a deep sleep mode. This mode reduces power consumption when the unit is idle, enhancing energy efficiency.

The DDS signal source unit is particularly suitable for electronic circuit prototype design and various test instruments. It serves as a versatile signal source, providing the necessary waveforms for testing and evaluating electronic circuits during the design and development process.
