LTC2634HUD-LMX10#PBF

Overview

The LTC2634HUD-LMX10#PBF 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, outputs reset to mid-scale in external reference mode.

Feature Summary

Quad 10-bit DACs with integrated 4.096V precision reference
Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
Automotive grade (-40°C to 125°C) with AEC-Q100 qualification
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 specific suffixes for package type (UD for QFN), temperature grade (H for Automotive), resolution (10), and reset configuration (LMX). Confirm RoHS compliance and lead-free status as indicated by the PBF suffix. Ensure the ordering code matches the required electrical specifications and packaging format.

Selection Notes

Select this part for applications requiring four independent 10-bit channels with high accuracy and wide operating temperature ranges. Choose between internal or external reference modes based on system requirements; LMX variants reset to mid-scale using an external reference. Ensure the supply voltage supports the 4.5V minimum requirement for the H-grade full-scale output.

Part Context

This component belongs to the LTC2634 family of quad DACs, which also offers 8-bit and 12-bit resolutions. Variants are available with different full-scale voltages (2.5V or 4.096V) and power-on reset behaviors (zero-scale or mid-scale). The HUD designation indicates the 16-lead QFN package and automotive temperature grade.
