LTC2634HUD-HMX8#PBF

Overview

The LTC2634HUD-HMX8#PBF is a quad 8-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 3-wire serial interface. Power-on reset defaults to mid-scale in external reference mode.

Feature Summary

Quad 8-bit DACs with integrated 4.096V precision reference
Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
Automotive qualified (AEC-Q100) for -40°C to 125°C operation
Power-on reset to mid-scale in external reference mode

Applications

Mobile Communications
Process Control and Industrial Automation
Automatic Test Equipment
Portable Equipment
Automotive Systems

Procurement Notes

Verify the H-grade temperature rating (-40°C to 125°C) and the H suffix indicating 4.096V full-scale output. Confirm the MUX power-on reset configuration matches system requirements. Ensure the QFN package soldering guidelines for the exposed pad are followed during assembly.

Selection Notes

Select this part for applications requiring four independent 8-bit outputs with high accuracy and automotive reliability. The 4.096V internal reference simplifies design by eliminating external components. Verify that the 4.5V minimum supply voltage aligns with the system power rails.

Part Context

This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The HUD suffix denotes the Automotive grade with extended temperature range, while the HMX8 specifies the 4.096V full-scale and mid-scale external reference reset behavior.

Replacement Considerations

LTC2634IUD-HMX8#PBF: Industrial temperature grade (-40°C to 85°C). LTC2634CUD-HMX8#PBF: Commercial temperature grade (0°C to 70°C). LTC2634HUD-LMX8#PBF: Resets to zero-scale instead of mid-scale.
