Overview
The LTC2634HUD-HMI8#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 mid-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
- SPI/MICROWIRE compatible 3-wire serial interface up to 50MHz
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Automatic Test Equipment
- Portable Equipment
- Automotive Systems
Procurement Notes
Verify the H-grade temperature rating and HMI power-on reset configuration against system requirements. Confirm the TRPBF suffix indicates tape and reel packaging for automated assembly. Ensure the 4.5V minimum supply voltage aligns with the target application's power rails.
Selection Notes
Select this part when high-accuracy 8-bit resolution is required alongside an integrated 4.096V reference. The H-grade ensures operation in harsh automotive environments. Consider the HMI power-on reset behavior if downstream circuits require a specific initial state upon power-up.
Part Context
This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in QFN and MSOP packages. The HUD suffix denotes the 16-lead QFN package, while HMI specifies the mid-scale reset in internal reference mode. The #TRPBF suffix confirms lead-free construction and tape-and-reel delivery.
Replacement Considerations
Direct replacements within the same family include LTC2634CUD-HMI8#TRPBF (commercial grade) or LTC2634IUD-HMI8#TRPBF (industrial grade). For external reference applications, consider the LMX variants. Verify pin compatibility and thermal performance when substituting.
