AD9833 GY-9833 Programmable Sine Square Wave DDS Signal Generator




The AD9833 is a low power, programmable waveform generator capable of producing
sine, triangular, and square wave outputs. Waveform generation is required in
various types of sensing, actuation, and time domain reflectometry (TDR)
applications. The output frequency and phase are software programmable, allowing
easy tuning. No external components are needed.

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

The AD9833 is written to via a 3-wire serial interface. This serial interface
operates at clock rates up to 40 MHz and is compatible with DSP and
microcontroller standards. The device operates with a power supply from 2.3 V to
5.5 V.

The AD9833 has a power-down function (SLEEP). This allows sections of the device
that are not being used to be powered down, thus minimizing the current
consumption of the part, e.g., the DAC can be powered down when a clock output
is being generated.
