PRELIMINARY TECHNICAL DATA

+2.5 V to +5.5 V, 25 MHz Low Power

Preliminary Technical Data

CMOSCompleteDDS

AD9833

with a power supply from +2.3 V to +5.5 V.

FEATURES

+2.3 V to +5.5 V Power Supply

25 MHz Speed

Tiny 10-Pin µSOIC Package

Serial Loading

Sinusoidal/Triangular DAC Output

Power-Down Option

Narrowband SFDR > 72 dB

20 mW Power Consumption at 3 V

Capability for phase modulation and frequency modula-

tion is provided. Frequency accuracy can be controlled to

one part in 0.25 billion. Modulation is effected by loading

registers through the serial interface.

The AD9833 offers a variety of output waveforms from

the VOUT pin. The SIN ROM can be bypassed so that a

linear up/down ramp is output from the DAC. If the SIN

ROM is not by-passed, a sinusoidal output is available.

Also, if a clock output is required, the MSB of the DAC

data can be output.

APPLICATIONS

Digital Modulation

Portable Equipment

Test Equipment

DDS Tuning

The digital section is internally operated at +2.5 V, irre-

spective of the value of VDD, by an on board regulator

which steps down VDD to +2.5 V, when VDD exceeds

+2.5 V.

The AD9833 has a power-down function (SLEEP). This

allows sections of the device which are not being used to

be powered down, thus minimising the current consump-

tion of the part e.g the DAC can be powered down when a

clock output is being generated.

GENERAL DESCRIPTION

This low power DDS device is a numerically controlled

oscillator employing a phase accumulator, a SIN ROM

and a 10-bit D/A converter integrated on a single

CMOS chip. Clock rates up to 25 MHz are supported

The AD9833 is available in a 10-pin µSOIC package.
