AD9832BRUZ-REEL

Overview

The AD9832BRUZ-REEL is a Direct Digital Synthesis (DDS) waveform generator integrated on a single CMOS chip. It features a 10-bit digital-to-analog converter (DAC), a phase accumulator, and an on-chip sine look-up table. The device supports clock rates up to 25 MHz with a resolution of 10 bits. It operates within a supply voltage range of 2.97 V to 5.5 V for both analog and digital sections. The component provides frequency accuracy controlled to one part in 4 billion and includes power-down options reducing consumption to 5 mW at 5 V. It utilizes a serial interface for register loading and modulation control.

Feature Summary

• Integrates a numerically controlled oscillator, sine look-up table, and 10-bit DAC on a single chip.
• Supports frequency and phase modulation capabilities via serial interface register loading.
• Includes a dedicated power-down option to minimize current consumption during idle periods.

Applications

• Frequency stimulus and waveform generation
• Low power RF and communications systems
• Liquid and gas flow measurement
• Sensory applications including proximity, motion, and defect detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure the procurement channel sources components directly from Analog Devices or authorized distributors to guarantee authenticity. Cross-reference the revision history in the datasheet to confirm compatibility with existing design specifications before finalizing orders.

Selection Notes

Select this component when a low-power DDS solution with a 25 MHz maximum clock rate is required. Verify that the 10-bit resolution meets the system's dynamic performance needs. Confirm that the serial interface timing parameters align with the host microcontroller's capabilities. Evaluate the power-down requirements against the application's duty cycle to leverage the low standby current feature effectively.

Part Context

The AD9832 belongs to the Analog Devices AD983x series of direct digital synthesizers. This family includes variants such as the AD9830, AD9831, AD9833, and AD9835, which differ primarily in clock speed, interface type, and package configuration. The AD9832 specifically targets applications requiring a balance between moderate speed and low power consumption in a compact form factor.

Replacement Considerations

The AD9832BRU is a leaded equivalent offering identical electrical specifications but in a different package format. For surface-mount designs requiring higher clock speeds, the AD9835 serves as a functional upgrade within the same series. Designers should verify pinout compatibility and thermal characteristics when substituting these parts.
