LTC2634HUD-HZ12#TRPBF

Overview

The LTC2634HUD-HZ12#TRPBF is a quad 12-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 from 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 temperature range, and communicates via a 50MHz SPI/MICROWIRE compatible 3-wire serial interface. This specific part number indicates an automotive-grade (H) component in a 16-lead QFN package with power-on reset to zero-scale.

Feature Summary

Quad 12-bit resolution with ±2.5 LSB maximum integral nonlinearity error
Integrated 4.096V full-scale reference with 10ppm/°C drift
Automotive AEC-Q100 qualified for -40°C to 125°C operation
Ultralow DAC-to-DAC crosstalk of 2.4nV•s

Applications

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

Procurement Notes

Verify the H suffix confirms the automotive temperature grade (-40°C to 125°C) and the Z suffix ensures power-on reset to zero-scale. Confirm the TRPBF suffix indicates tape and reel packaging with lead-free compliance. Cross-reference the datasheet Rev E specifications for settling time and noise density relevant to the 4.096V full-scale configuration.

Selection Notes

Select this model when a 4.096V internal reference is required alongside automotive reliability standards. Ensure the system supply voltage remains within the 4.5V to 5.5V range specified for the H-grade variant. Consider the 16-lead QFN package dimensions if board space is constrained, noting the exposed pad must be soldered to PCB ground.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 8-, 10-, and 12-bit resolutions. The HUD designation specifies the 16-lead QFN package and automotive temperature grade. The HZ12 core defines the 4.096V full-scale range and zero-scale power-on reset behavior, distinguishing it from mid-scale reset or external reference variants.
