LTC2634HUD-LMI10#TRPBF

Overview

The LTC2634HUD-LMI10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 125°C automotive temperature range, and communicates via a 50MHz SPI/MICROWIRE compatible interface. Upon power-up, it resets to mid-scale in internal reference mode.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference
• Automotive grade (-40°C to 125°C) with AEC-Q100 qualification
• Rail-to-rail output buffers and ultralow crosstalk (2.4nV•s)
• Power-on reset to mid-scale in internal reference mode

Applications

• Automotive systems
• Process control and industrial automation
• Portable equipment

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the H-grade designation matches the required -40°C to 125°C operating temperature range for your application environment.

Selection Notes

Select this part when a 4.096V full-scale output is required with mid-scale initialization. Ensure the system supply voltage remains within the 4.5V to 5.5V range specified for the H-grade variant to maintain performance specifications.

Part Context

This component belongs to the LTC2634 family, which offers 8-, 10-, and 12-bit resolutions in both QFN and MSOP packages. The HUD package denotes the 16-lead QFN form factor, while the LMI suffix specifies the mid-scale reset behavior in internal reference mode.

Replacement Considerations
