AD5930YRUZ

Overview

The AD5930YRUZ is a waveform generator with programmable frequency sweep and output burst capability, utilizing embedded digital processing for enhanced frequency control. It generates synthesized analog or digital frequency-stepped waveforms using a 24-bit pipelined DDS core and a 10-bit DAC. The device operates on a 2.3 V to 5.5 V power supply and features a 3-wire serial interface supporting clock rates up to 40 MHz. Key specifications include an update rate of 50 MSPS, an output frequency up to 25 MHz, and a signal-to-noise ratio of 60 dB at fMCLK = 50 MHz. It consumes only 8 mA during operation and offers a standby mode with 20 µA current draw.

Feature Summary

• Programmable frequency profile eliminates continuous DSP/microcontroller write cycles
• Supports sinusoidal, triangular, and square wave outputs with known phase start
• Burst and listen capability allows predefined output duration followed by midscale return
• Automotive temperature range from -40°C to +125°C

Applications

• Frequency sweeping/radar
• Network/impedance measurements
• Incremental frequency stimulus
• Proximity and motion detection
• BFSK frequency bursting/pulse trains

Procurement Notes

Verify the specific suffix YRUZ corresponds to the automotive grade (Y) in the 20-lead TSSOP package. Confirm RoHS compliance status as detailed in the manufacturer's documentation. Ensure the ordering quantity matches the tube packaging format specified for this part number variant.

Selection Notes

Select the AD5930YRUZ when pre-programmed frequency sweeps are required to minimize host processor overhead. The Y-grade designation ensures operation across the extended automotive temperature range of -40°C to +125°C. Verify that the 10-bit resolution and 25 MHz maximum output frequency meet system requirements.

Part Context

The AD5930YRUZ belongs to the AD5930 series of direct digital synthesizers manufactured by Analog Devices. It is designed as a low-power solution for waveform generation, integrating a DDS core and DAC into a single chip. The Y suffix indicates the automotive qualification grade, distinguishing it from commercial variants while maintaining identical functional specifications.
