Product details

DDS core for programmable waveform generation

The AD9833BRMZ-REEL is a 25 MHz direct digital synthesis (DDS) IC from Analog Devices that generates sine, triangle, and square wave outputs with 10-bit resolution and a 28-bit tuning word for fine frequency control.

Clock ceiling and frequency resolution

With a 25 MHz master clock, the 28-bit tuning word yields a frequency resolution of about 0.1 Hz — fine enough for swept-sine impedance measurements or precision audio tone generation without an external PLL. The 10-bit DAC output sets the amplitude resolution; for applications needing lower noise or higher SFDR, the AD9834 (12-bit DAC, same pinout) is a drop-in alternative worth evaluating.

Package and supply integration

The 10-MSOP (3.00 mm width) surface-mount package requires a standard MSOP-10 land pattern. Supply decoupling should follow the datasheet recommendation: a 0.1 µF ceramic close to each supply pin and a 10 µF bulk capacitor on the main rail. The wide supply tolerance (2.3 V to 5.5 V) gives margin when the rail droops under load.

Frequently asked questions

What is the closest functional second-source for the AD9833BRMZ-REEL?

The AD9833BRMZ-REEL7 is functionally identical — same 25 MHz master clock, 10-bit DAC, 28-bit tuning word, and 10-MSOP package — differing only in the Digi-Reel packaging option. For a tube-packaged variant, the AD9833BRMZ is the same die in a tube. The automotive-grade AD9833WBRMZ-REEL carries the same specs with AEC-Q100 qualification.

Is the AD9833 compatible with 3.3 V logic?

Yes. The supply range of 2.3 V to 5.5 V includes 3.3 V. The digital inputs (FSYNC, SCLK, SDATA) are 3.3 V tolerant when the part is powered at 3.3 V. No level shifters are needed when interfacing with a 3.3 V MCU or FPGA.
