LTC2654BIUF-H16#TRPBF

Overview

The LTC2654BIUF-H16#TRPBF is a quad 16-bit rail-to-rail digital-to-analog converter (DAC) from Analog Devices, housed in a 20-lead 4mm × 4mm QFN package. It features an integrated reference yielding a full-scale output of 4.096V and operates on a 4.5V to 5.5V supply. The device supports SPI/Microwire interfaces up to 50MHz, offers ±4LSB maximum INL, and includes power-on reset options for zero or mid-scale initialization.

Feature Summary

• Quad 16-bit resolution with integrated 10ppm/°C max reference
• Rail-to-rail output buffers with ultralow crosstalk (<3nV•s)
• SPI/Microwire compatible 4-wire serial interface
• Selectable internal or external reference modes

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Instrumentation
• Automatic Test Equipment
• Automotive

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the BIUF designation corresponds to the industrial temperature grade (-40°C to 85°C) and the QFN package type required for the design.

Selection Notes

Select this part for applications requiring four independent 16-bit channels with high precision. Ensure the system supply voltage remains within the 4.5V to 5.5V range specified for the -H variant. Consider the external reference option if a different full-scale voltage is needed.

Part Context

This component belongs to the LTC2654 family of quad DACs. It shares architectural similarities with other variants like the LTC2654BIGN-L16#PBF but differs in package type (QFN vs SSOP), temperature grade (Industrial vs Commercial), and full-scale voltage configuration (4.096V vs 2.5V).

Replacement Considerations
