Product details

What this DDS brings to a signal chain

The AD9851BRSZRL is a complete direct digital synthesizer (DDS) from Analog Devices, integrating a 10-bit DAC on-chip with a 180 MHz master clock. The 32-bit tuning word gives you sub-Hz frequency resolution across the output range — useful for agile signal generation in communications, test equipment, or sensor excitation. It runs from a 2.7V to 5.25V supply, so you can drop it into a 3.3V or 5V rail without a separate regulator.

It is ROHS3 compliant, which simplifies export and environmental compliance. Supplied in Tape & Reel (TR) or Cut Tape (CT) options, the 28-SSOP package (0.209" body width, 5.30 mm) is a common footprint that reflow solders without special handling.

Frequently asked questions

How can I order the AD9851BRSZRL or check current availability?

The AD9851BRSZRL is an active Analog Devices part, so it is available through our sourcing desk. Submit an RFQ with your target quantity and preferred packaging (Tape & Reel or Cut Tape) — we will confirm pricing and lead time against your BOM line. No stock-holding claim is made here; availability is confirmed per order.

Is the AD9851BRSZRL a direct replacement for the AD9851BRSZ (tube version)?

Electrically identical — same 180 MHz master clock, same 10-bit DAC, same 28-SSOP package. The only difference is the shipping format: AD9851BRSZRL comes in Tape & Reel (suitable for automated pick-and-place), while the AD9851BRSZ is in a tube. If your assembly line feeds from reels, order the -RL suffix; if you hand-place or use a tube feeder, the tube version works. Both are active and ROHS3 compliant.

What is the maximum clock frequency of the AD9851?

The master clock (fclk) is rated at 180 MHz. That sets the Nyquist limit at 90 MHz for the output sine wave, though practical output bandwidth is typically limited to about 70 MHz to keep spurious levels manageable.

Is the AD9851BRSZRL RoHS compliant?

Yes, it is ROHS3 compliant. No exemptions or exceptions listed — it meets the current EU RoHS directive for lead, mercury, cadmium, and other restricted substances.
