AD7249BRZ-REEL

Overview

The AD7249BRZ-REEL is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, packaged in a 16-lead SOIC. It integrates on-chip voltage amplifiers and a Zener voltage reference, eliminating the need for external trimming. The device supports single or dual supply operation, providing selectable output ranges of 0 V to +5 V, 0 V to +10 V, or ±5 V. It features a serial interface allowing data rates up to 2 MHz, enabling a DAC update rate of 125 kHz. The B version operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

Dual 12-bit CMOS DAC channels with integrated voltage reference and output amplifiers
Three selectable output ranges per channel: 0 V to +5 V, 0 V to +10 V, and ±5 V
Serial interface compatible with DSP processors and microcontrollers, supporting 125 kHz update rates
Clear function resets outputs to a known state, useful for power-on reset

Applications

Process control systems
Industrial automation equipment
Digital signal processing systems
Input/output ports

Procurement Notes

Verify the specific suffix 'REEL' indicates tape and reel packaging when ordering. Confirm that the B version meets the required -40°C to +85°C operating temperature range. Ensure the application design accounts for the specified power supply tolerances and decoupling requirements to maintain performance specifications.

Selection Notes

Select this component for applications requiring two independent 12-bit DACs with buffered outputs in a compact package. Consider the serial interface requirements and ensure the host processor supports the necessary clocking protocol. Verify that the desired output voltage range matches the available configurations and that the power supply rails are compatible with the selected range.

Part Context

The AD7249 belongs to the DACPORT family of monolithic CMOS DACs. The BRZ designation indicates the B grade version with industrial temperature rating (-40°C to +85°C) and RoHS-compliant lead-free packaging. The REEL suffix specifies the tape and reel shipping format, distinct from tube packaging options like the AD7249BRZ.
