LTC2635HUD-LMI12#TRPBF

Overview

The LTC2635HUD-LMI12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated precision reference with a full-scale output of 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes.

Feature Summary

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

Applications

• Process control and industrial automation
• Portable equipment
• Automotive systems

Procurement Notes

Verify that the component matches the Automotive Temperature Grade (H) and the specific Power-On Reset configuration for Mid-Scale in Internal Reference Mode (MI). Confirm the package type is the 16-lead QFN and the suffix indicates Tape and Reel packaging.

Selection Notes

Select this part when a quad-channel DAC with high accuracy and low drift is required for automotive applications. The 2.5V full-scale output suits single-supply systems operating between 4.5V and 5.5V. Ensure the design accommodates the 16-pin QFN footprint and utilizes the I²C interface constraints.

Part Context

This component belongs to the LTC2635 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The 'H' designation specifies the automotive temperature range and 4.5V minimum supply requirement, while 'LMI12' defines the 2.5V internal reference, mid-scale power-on reset behavior, and 12-bit resolution.
