AD9833BRMZ

Overview

The AD9833BRMZ is a low-power, programmable waveform generator from Analog Devices Inc., housed in a 10-lead MSOP package. It operates on a 2.3 V to 5.5 V supply and consumes 12.65 mW at 3 V. The device features a 10-bit DAC with an update rate of 25 MSPS and generates sine, triangular, and square waves within a 0 MHz to 12.5 MHz output frequency range. It utilizes a 28-bit frequency register for precise tuning and communicates via a 3-wire serial interface supporting clock rates up to 40 MHz. The component functions across an extended temperature range of −40°C to +105°C.

Feature Summary

• Digitally programmable frequency and phase control
• Integrated power-down function for current minimization
• No external components required for basic operation
• AEC-Q100 qualified for automotive applications

Applications

• Frequency stimulus and waveform generation
• Liquid and gas flow measurement
• Proximity, motion, and defect detection sensing
• Time domain reflectometry (TDR) applications

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and qualification status. Confirm that the ordering code matches the exact voltage and temperature specifications required for the target application environment. Ensure compatibility with existing serial interface protocols before finalizing procurement decisions.

Selection Notes

Select this component when a low-power DDS solution is required for generating multiple waveform types without external analog components. Consider the 28-bit resolution and 25 MHz clock capability for applications demanding high frequency accuracy. Verify that the 10-lead MSOP package fits the available PCB space and thermal requirements.

Part Context

This part belongs to the AD9833 series of direct digital synthesis devices. It is designed as a fully integrated CMOS chip combining a numerically controlled oscillator, SIN ROM, and a 10-bit DAC. The BRMZ variant specifically denotes the industrial temperature grade and MSOP packaging configuration offered by Analog Devices.

Replacement Considerations

Check for AD9833WBRMZ-REEL for reel-packaged alternatives. Evaluate AD9837 or AD9850 if higher performance or different pinouts are needed, ensuring functional compatibility with existing system designs.
