AD7849BRZ-REEL

Overview

The AD7849BRZ-REEL is a 16-bit serial input multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates with analog supply voltages of ±14.25 V to ±15.75 V and a digital supply of 4.75 V to 5.25 V. The device features a versatile three-wire serial interface, guaranteed monotonicity over temperature, and an output that clears to 0 V during power-up or power-down sequences. It is housed in a 20-lead SOIC package and includes internal voltage monitoring for system reset control.

Feature Summary

• 16-bit resolution with guaranteed monotonicity
• Serial interface compatible with opto-isolators via daisy-chain capability
• Output clamped to 0 V during power transitions via internal voltage monitor
• Configurable binary or two's complement coding via BIN/COMP pin

Applications

• Industrial process controls
• PC analog I/O boards
• Instrumentation systems

Procurement Notes

Verify the specific grade suffix against the datasheet ordering guide to confirm 16-bit resolution and accuracy specifications. Ensure the reel packaging matches the required quantity for production runs. Confirm RoHS compliance status as per the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when a high-resolution, low-glitch DAC with serial interface is required. The B-grade version offers ±6 LSB relative accuracy at 25°C. Consider the external reference requirements and the need for bipolar or unipolar output configurations based on the application's voltage range needs.

Part Context

This part belongs to the AD7849 series of multiplying DACs. The BRZ suffix indicates a 20-lead SOIC package with RoHS compliance. The REEL suffix denotes tape-and-reel packaging. Other grades include A (14-bit) and C (16-bit), offering different accuracy and linearity specifications.
