LTC2634HUD-HZ8#TRPBF

Overview

The LTC2634HUD-HZ8#TRPBF 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 zero-scale in internal reference mode.

Feature Summary

Quad 8-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 guaranteed monotonicity
Power-on reset to zero-scale in internal reference mode

Applications

Mobile communications
Process control and industrial automation
Automatic test equipment
Portable equipment
Automotive systems

Procurement Notes

Verify the H-grade designation for the extended -40°C to 125°C operating range and the Z suffix for zero-scale power-on reset behavior. Confirm the TRPBF suffix indicates tape-and-reel packaging with lead-free compliance. Ensure the 4.5V minimum supply voltage aligns with system power rails.

Selection Notes

Select this part when four independent 8-bit outputs are required with high accuracy and automotive reliability. The 4.096V full-scale range suits applications needing higher resolution than 2.5V variants without requiring external references. Verify that the 50MHz serial clock speed meets system timing requirements.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The HUD package denotes a 16-lead QFN form factor. The H suffix specifies the 4.096V full-scale internal reference, while Z indicates zero-scale power-on reset. Other variants include L-grade commercial parts and MI/MX reset options.

Replacement Considerations

Direct replacements within the same family include LTC2634CUD-HZ8#PBF (commercial grade) or LTC2634IUD-HZ8#PBF (industrial grade). For different resolutions, consider LTC2634HUD-HZ10#TRPBF (10-bit) or LTC2634HUD-HZ12#TRPBF (12-bit), ensuring pin compatibility and supply voltage constraints are met.
