AD9833BRM-REEL7

Overview

The AD9833BRM-REEL7 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 produces sinusoidal, triangular, and square wave outputs ranging from 0 MHz to 12.5 MHz. Frequency and phase are digitally programmable via a 3-wire SPI interface compatible with DSP standards. It includes a 28-bit frequency register for high resolution and supports power-down modes to minimize current consumption.

Feature Summary

• Digitally programmable frequency and phase control
• Low power consumption with dedicated sleep mode
• Integrated 10-bit DAC with onboard 200 Ω load resistor
• Standard 3-wire serial interface compatible with DSP and microcontrollers

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 official documentation to confirm packaging type and automotive qualification status. Ensure the component matches the required temperature range and voltage specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a low-power, software-tunable waveform generator is required without external passive components. It is suitable for applications needing sine, triangle, or square waves up to 12.5 MHz. Consider the 10-lead MSOP package constraints and the need for a 3-wire serial interface compatible with the host processor.

Part Context

This part belongs to the AD9833 series of direct digital synthesis (DDS) devices. It is designed for applications requiring precise frequency and phase control with minimal external circuitry. The BRM variant indicates industrial temperature range operation within the standard MSOP footprint.

Replacement Considerations

Check for AD9833BRMZ or AD9833WBRMZ-REEL as potential pin-compatible alternatives with different packaging or automotive qualifications. Verify functional equivalence regarding output frequency range and power consumption before substitution.
