LTC2668IUJ-16#PBF

Overview

The LTC2668IUJ-16#PBF is a 16-channel, 16-bit digital-to-analog converter (DAC) from Analog Devices. It features SoftSpan technology allowing independently programmable output ranges of 0V to 5V, 0V to 10V, ±2.5V, ±5V, or ±10V. The device integrates a precision 2.5V reference with a maximum temperature coefficient of 10ppm/°C and built-in rail-to-rail output buffers capable of driving ±10mA. It operates on analog supplies ranging from ±4.5V to ±15.75V and includes A/B toggle capability via software or dedicated pin.

Feature Summary

16 independent channels with 16-bit resolution and ±4LSB maximum INL error
SoftSpan™ technology for five selectable output ranges up to ±10V
Integrated 2.5V reference with 10ppm/°C max temperature coefficient
Rail-to-rail output buffers with ±10mA drive capability

Applications

Optical networking systems
Precision instrumentation
Data acquisition systems
Automatic test equipment
Process control and industrial automation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging when sourcing this component. Confirm that the IUJ designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure the ordering information matches the required package type, which is a 40-lead QFN.

Selection Notes

Select the LTC2668IUJ-16#PBF for applications requiring high channel density and flexible voltage ranges. The industrial grade ensures operation in wider temperature environments compared to commercial variants. Consider the integrated reference for cost-sensitive designs where external precision references are not mandatory.

Part Context

This part belongs to the LTC2668 family of SoftSpan DACs. The 'I' suffix denotes the industrial temperature range, while 'UJ' specifies the 40-lead plastic QFN package. The '#PBF' suffix confirms lead-free manufacturing compliance. Other variants include commercial and automotive grades with different temperature specifications.

Replacement Considerations

Direct replacements within the same family include the LTC2668CUJ-16#PBF for commercial temperature ranges and the LTC2668HUJ-16#PBF for automotive/high-temperature applications. Ensure thermal management meets the junction temperature requirements for the selected grade.
