AD7849CRZ-REEL

Overview

The AD7849CRZ-REEL is a 16-bit serial input multiplying digital-to-analog converter (DAC) manufactured by Analog Devices. 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 settling time of 7 μs to 0.006% FSR. It includes internal power-up/down clamping to 0 V and supports daisy-chain configurations via the SDOUT pin. The component is housed in a 20-lead SOIC package.

Feature Summary

16-bit resolution with guaranteed monotonicity over the specified temperature range
Versatile serial interface supporting standalone and daisy-chain modes
Internal voltage monitor provides automatic output clamping to 0 V during power transitions
Configurable binary or two's complement coding via the BIN/COMP pin

Applications

Industrial process controls
PC analog I/O boards
Instrumentation systems

Procurement Notes

Verify that the ordering suffix REEL indicates reel packaging rather than tube packaging. Confirm the specific grade corresponds to the C version specifications for linearity and accuracy. Ensure the procurement documentation matches the 20-lead SOIC physical footprint requirements for the target PCB design.

Selection Notes

Select this part when 16-bit precision and serial connectivity are required. The C version offers ±4 LSB relative accuracy at 25°C. Consider the external reference requirements as the AD7849 utilizes an external reference input. Evaluate the need for daisy-chaining capabilities if multiple channels are present in the system architecture.

Part Context

This component belongs to the AD7849 series of multiplying DACs. The 'C' designation identifies the specific performance grade regarding linearity and accuracy parameters. The 'REEL' suffix denotes the specific tape-and-reel packaging format used for automated surface-mount assembly processes.
