AD9833BRMZ-REEL

Overview

The AD9833BRMZ-REEL 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 sinusoidal, triangular, and square wave outputs ranging from 0 MHz to 12.5 MHz. It utilizes a 28-bit frequency resolution (0.1 Hz at 25 MHz reference clock) and includes a 3-wire SPI interface compatible with DSP standards. The component supports extended industrial temperatures from −40°C to +105°C and offers power-down options.

Feature Summary

• Digitally programmable frequency and phase control via software
• Integrated 3-wire serial interface compatible with standard DSP protocols
• Low power consumption with dedicated sleep mode for unused sections
• No external components required for basic waveform generation

Applications

• Frequency stimulus and waveform generation
• Liquid and gas flow measurement systems
• Proximity, motion, and defect detection sensors
• Time domain reflectometry (TDR) applications
• Test and medical equipment signal sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm packaging type and automotive qualification status. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the pinout configuration with your PCB layout design to guarantee correct alignment with the 10-lead MSOP footprint.

Selection Notes

Select this component when a low-power DDS solution is required for generating precise sine, triangle, or square waves. It is suitable for designs needing digital frequency tuning without external analog components. Consider the 28-bit resolution for high-frequency accuracy needs. Verify that the operating voltage range aligns with your system's power supply constraints.
