This document explains how to interface the Analog Devices AD9833 programmable waveform generator with microcontrollers using SPI communication.
This document discusses the interface of the AD9833, a programmable waveform generator, with microcontrollers. It includes information on using the AD9833 with various microcontrollers such as Atmel 89s52, PIC, and others, along with details on SPI communication, signal generation, and hardware setup. The text highlights the device's capability to produce sine, triangular, and square wave outputs with software-programmable frequency and phase.
| Output Waveforms | sine, triangular and square wave |
|---|---|
| Interface Type | 3 wire serial interface |
| Clock Rate | up to 40 MHz |
| Power Supply Range | 2.3 V to 5.5 V |
| Power Down Function | SLEEP |
The device is controlled via a 3-wire serial peripheral interface (SPI).
With a 1 MHz clock rate, the device can be tuned to a resolution of 0.004 Hz.
