LTC2635HUD-HMI12#PBF

Overview

The LTC2635HUD-HMI12#PBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in a 16-lead QFN package. 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 and guarantees monotonicity over the automotive temperature range of –40°C to 125°C. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. A power-on reset circuit initializes outputs to mid-scale in internal reference mode.

Feature Summary

Quad 12-bit resolution with maximum INL error of ±2.5 LSB
Integrated 4.096V full-scale reference with 10ppm/°C drift
Automotive temperature grade (-40°C to 125°C)
Power-on reset to mid-scale in internal reference mode

Applications

Process control and industrial automation
Power supply margining
Portable equipment
Automotive systems

Procurement Notes

Verify the H suffix confirms the automotive temperature range and 4.096V internal reference configuration. Confirm the UD suffix indicates the 16-pin QFN package type. Ensure the #PBF designation matches lead-free requirements for the specific manufacturing batch.

Selection Notes

Select this part when a 4.096V full-scale output is required with high linearity accuracy. The H-grade variant is necessary for operations exceeding 70°C or below 0°C. Verify that the 4.5V minimum supply voltage aligns with the system power rails, as the L-grade supports lower voltages down to 2.7V.

Part Context

This component belongs to the LTC2635 family of quad DACs. The HUD-HMI12 designation specifies the 12-bit resolution, H-grade automotive temperature rating, UD QFN package, and mid-scale power-on reset behavior. Other variants include L-grade for lower voltage operation and different reset options like zero-scale or high-impedance states.
