AD5668SRUZ-EP-1RL7

Overview

The AD5668SRUZ-EP-1RL7 is an enhanced product, octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) in a 16-lead TSSOP package. It operates from a single 2.7 V to 5.5 V supply and features an on-chip 1.25 V reference with 5 ppm/°C temperature coefficient, providing a 2.5 V full-scale output range. The device supports military temperature ranges (-55°C to +125°C), includes power-on reset to zero scale or midscale, and offers low power-down current consumption of 400 nA at 5 V.

Feature Summary

• Octal, 16-bit resolution with ±21 LSB INL accuracy
• On-chip 1.25 V reference with 5 ppm/°C drift
• Military temperature range: -55°C to +125°C
• Power-down mode consumes 400 nA at 5 V

Applications

• Defense applications
• Aerospace systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging and 'Z' denotes RoHS compliance per the manufacturer's ordering guide. Confirm that the Enhanced Product (EP) designation ensures controlled manufacturing baseline and qualification data availability for defense and aerospace requirements.

Selection Notes

Select this component when military-grade temperature stability (-55°C to +125°C) and high channel count are required. The internal 1.25 V reference limits the maximum output span to 2.5 V; use external references if higher voltage ranges are needed. Ensure the 16-lead TSSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the AD5668-EP family of octal DACs. The 'S' indicates the industrial/military grade variant, 'RU' specifies the 16-lead TSSOP package, 'Z' confirms RoHS compliance, and 'RL7' designates the tape and reel packaging format.

Replacement Considerations

Standard commercial versions like AD5668ARUZ-2 offer similar functionality but lack the extended temperature range and controlled manufacturing baseline required for EP applications.
