LTC2635HUD-HMI10#PBF

Overview

The LTC2635HUD-HMI10#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 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 automotive temperature range, and ultralow crosstalk between DACs (3nV•s). Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Power-on reset options include mid-scale or high-impedance states.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Automotive temperature grade (-40°C to 125°C)
• Ultralow DAC-to-DAC crosstalk (3nV•s)

Applications

• Process control and industrial automation
• Power supply margining
• Portable equipment

Procurement Notes

Verify the H suffix confirms the 4.5V–5.5V operating range and 4.096V internal reference. Confirm the MI suffix specifies power-on reset to mid-scale in internal reference mode. Ensure the #PBF designation indicates lead-free construction and the absence of tape-and-reel packaging.

Selection Notes

Select this part for applications requiring four independent channels with high accuracy and low crosstalk. The H-grade variant is necessary for systems operating above 4.5V or requiring the 4.096V full-scale range. Verify that the I²C address configuration pins (CA0-CA2) can be set to avoid bus conflicts in multi-device designs.

Part Context

This component belongs to the LTC2635 family of quad DACs. The HUD package denotes a 16-lead 3mm × 3mm QFN form factor. The HMI10 specification identifies it as the 10-bit resolution variant with mid-scale power-on reset behavior.
