The AD9833 is a low power programmable waveform generator capable of producing sine, triangle, and square wave outputs. It is suitable for applications requiring precise frequency and phase control, such as waveform detection, signal generation, and time domain reflectometry (TDR). The device is software programmable and requires no external components for operation.The 28-bit frequency register provides fine resolution: 0.1 Hz with a 25 MHz clock, and 0.004 Hz with a 1 MHz clock. The AD9833 features a standard serial interface that enables direct communication with microprocessors and microcontrollers. Data is written to the device using an external serial clock, and the interface supports clock speeds up to 40 MHz, ensuring compatibility with DSPs and other digital systems.Key specifications include:- Digitally programmable frequency and phase- Power consumption: 12.65 mW at 3 V- Output frequency range: 0 MHz to 12.5 MHz- Frequency resolution: 0.1 Hz (with 25 MHz reference clock)- Output types: Sine, triangle, and square waves- Supply voltage: 2.3 V to 5.5 V- No external components requiredThe device includes a power-down function (SLEEP mode) that reduces power consumption by disabling internal circuitry when not in use, such as during output clock generation.Operating temperature range: -40C to +105C Typical operating conditions: 25C Maximum update rate: 25 MHz VOUT maximum: 0.65 V VOUT minimum: 38 mV VOUT temperature coefficient: 200 ppm/C High-level input voltage: 1.7 V to 2.8 V Low-level input voltage: 0.5 V to 0.7 V Input capacitance: 3 pF Material: PCB board Color: As shown Package Contents: 1 x DDS Module 1 x Pin Header Note: Only the items listed above are included in the package.
