AD5932YRUZ

Overview

The AD5932YRUZ is a programmable waveform generator featuring a 10-bit DAC and embedded digital processing for frequency scanning. It operates on a 2.3 V to 5.5 V supply with typical current consumption of 6.7 mA. The device supports output frequencies up to 25 MHz via a master clock input. Key electrical parameters include a signal-to-noise ratio of 60 dB, total harmonic distortion of -53 dBc, and spurious-free dynamic range of -52 dBc (wideband). It utilizes a 3-wire serial interface operating at up to 40 MHz and provides sinusoidal, triangular, or square wave outputs.

Feature Summary

• Pre-programmable frequency profiles eliminate continuous DSP/microcontroller write cycles during operation.
• Phase-continuous waveform generation allows easy determination of phase shifts across frequency steps.
• Flexible control modes allow automatic internal stepping or external stepping via the CTRL pin.
• Integrated standby function reduces power consumption to 20 µA when not in use.

Applications

• Frequency scanning and radar systems
• Network and impedance measurements
• Incremental frequency stimulus applications
• Proximity and motion sensory applications

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape-and-reel packaging if required by assembly equipment. Confirm that the Y-grade designation meets the automotive temperature range requirements of -40°C to +125°C for the target environment. Ensure the TSSOP-16 package dimensions align with the PCB footprint design specifications.

Selection Notes

Select this component when a pre-programmable scan profile is needed to reduce host processor load. Choose the Y-grade version for extended temperature operation up to +125°C. Verify that the 10-bit resolution and 25 MHz maximum output frequency meet the system's spectral purity and speed requirements.

Part Context

The AD5932YRUZ belongs to the Analog Devices AD5932 series of direct digital synthesis waveform generators. It shares functional similarities with the AD5930 and AD5933 but offers specific integration for frequency scanning without external components. The YRUZ variant denotes the automotive grade temperature range and the 16-lead TSSOP package configuration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for current availability and potential obsolescence notices regarding the AD5932 series.
