AD7849ARZ-REEL

Overview

The AD7849ARZ-REEL is a 16-bit serial input multiplying digital-to-analog converter (DAC) from Analog Devices. It features guaranteed monotonicity over the specified temperature range and utilizes a versatile three-wire serial interface compatible with opto-isolators. The device includes internal output control during power-up and power-down sequences, clamping VOUT to 0 V via low impedance. It supports daisy-chain configurations through an SDOUT pin and allows selection between binary and two's complement coding. The component operates with analog supplies of ±14.25 V to ±15.75 V and a digital supply of 4.75 V to 5.25 V.

Feature Summary

16-bit resolution with guaranteed monotonicity
Versatile 3-wire serial interface supporting daisy-chaining
Internal output clamp to 0 V during power transitions
Configurable binary or two's complement data coding

Applications

Industrial process controls
PC analog I/O boards
Instrumentation systems

Procurement Notes

Verify that the REEL suffix indicates tape-and-reel packaging for automated assembly. Confirm the A-grade specification aligns with design requirements, noting that while the part number denotes 16-bit capability, the A grade guarantees monotonicity to 14 bits. Ensure external reference voltages match the specified ranges for optimal performance.

Selection Notes

Select this component when a high-resolution, serially controlled DAC with safe startup behavior is required. The A grade offers cost advantages but limits guaranteed monotonicity to 14 bits; B and C grades guarantee full 16-bit monotonicity. Verify that the system can provide the necessary ±15 V analog supplies and 5 V digital logic levels.

Part Context

This part belongs to the AD7849 family of multiplying DACs. The 'A' suffix in AD7849AR indicates the temperature and accuracy grade, while 'RZ' specifies the SOIC-20 package and RoHS compliance. The '-REEL' designation confirms the shipping format is a reel rather than a tube.
