LTC2635HMSE-LMI12#PBF

Overview

The LTC2635HMSE-LMI12#PBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) in a 10-lead MSOP package. 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 communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes.

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 options including mid-scale or high-impedance states

Applications

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

Procurement Notes

Verify the specific ordering suffix LMI12 confirms the 12-bit resolution, mid-scale power-on reset behavior, and internal reference configuration. Confirm the MSE package designation matches the required 10-lead MSOP footprint and pinout for PCB layout compatibility.

Selection Notes

Select this part when a 4.096V full-scale range is required with an internal reference. Ensure the system supply voltage remains within the 4.5V to 5.5V range specified for the H-grade variant. Verify that the I²C address configuration via CA0-CA2 pins meets the system addressing requirements.

Part Context

This component belongs to the LTC2635 family of quad DACs. The HMSE designation indicates the H-grade automotive temperature rating and the MSE 10-lead MSOP package. The LMI12 suffix specifies the 12-bit resolution and mid-scale power-on reset mode with an internal reference.

Replacement Considerations

Direct replacements within the same family include other LTC2635 variants with different resolutions (8-bit or 10-bit) or reset configurations (zero-scale or high-impedance). Cross-package equivalents are available in the 16-pin QFN format.
