Product Overview
The AD9831ASTZ-REEL is an integrated DDS numerically controlled oscillator by Analog Devices. It integrates a 32-bit phase accumulator, sine lookup table and 10-bit DAC on single CMOS silicon, supporting a maximum 25 MHz master clock for high-precision analog waveform output. Its parallel bus supports glitch-free, phase-continuous frequency hopping and FSK/GFSK/BPSK modulation, with dual frequency registers and four phase offset registers for flexible tuning. Housed in a lead-free 48-lead 7 mm × 7 mm TQFP and supplied in tape-and-reel packaging for SMT production, it acts as a high-performance signal generator for communication transceivers, test instruments and industrial measurement equipment.
Core Advantages
Ultra-High Frequency Resolution
Incorporates a deep 32-bit phase accumulator that allows sub-hertz frequency tuning increments, achieving an exceptional level of precision for critical synchronization and sweeping functions.
Integrated 10-Bit High-Speed DAC
Features an onboard premium analog reconstruction DAC, eliminating the need for complex multi-chip layouts and minimizing signal loss between digital synthesis registers and analog filtering stages.
Agile Parallel Microprocessor Interface
Equipped with a high-speed parallel bus architecture that allows instantaneous data register updates, supporting dynamic real-time frequency-shift keying (FSK) and phase-shift keying (PSK) operations.
Built-In Hardware Power-Down Pin
Integrated dedicated sleep pin cuts core operating current drastically under idle states, reducing thermal load for closed-chassis and portable battery-powered electronic hardware.

Frequently Asked Questions
Q1: Is your currently available stock of the AD9831ASTZ-REEL 100% original and authentic?
A: Yes, we guarantee that all AD9831ASTZ-REEL components in our inventory are 100% brand-new, factory-original units directly from Analog Devices. Every batch is traceable and is shipped in original ESD-compliant tape-and-reel segments inside sealed protective bags to guarantee absolute lead plane integrity.
Q2: What do the suffixes “Z” and “REEL” indicate in the part number string?
A: The “Z” suffix indicates that the 48-TQFP package meets modern environmental mandates and utilizes lead-free/RoHS-compliant finishings. The “-REEL” suffix specifies that the components are packed on a standard continuous emboss tape wound onto a plastic reel, matching automated high-speed SMT assembly processing standards.
Q3: Can the frequency registers of the AD9831ASTZ-REEL be updated phase-continuously?
A: Yes, absolutely. The internal architecture utilizes dual independent frequency registers. Software can write the next required tuning word to the inactive register via the parallel interface, and then toggle the dedicated FSELECT hardware pin. This triggers an instantaneous, glitch-free, and phase-continuous step to the new target frequency.
Q4: How can our design engineers request an official ADI technical datasheet, software simulation scripts, or request bulk volume pricing tiers?
A: Please fill out the Quick Inquiry web form found directly on this webpage. Our technical support desk will assess your design constraints and reply with complete data documentation and custom commercial quotes within 24 hours.
