LTC2635CMSE-HMI12#TRPBF

Overview

The LTC2635CMSE-HMI12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead MSOP 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, 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. Power-on reset defaults to mid-scale.

Feature Summary

• Quad 12-bit resolution with ±2.5 LSB maximum INL error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Automotive grade operation from –40°C to 125°C
• Power-on reset configured for mid-scale output

Applications

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

Procurement Notes

Verify the specific suffix 'HMI12' confirms the 4.096V internal reference, 12-bit resolution, and mid-scale power-on reset behavior. Confirm the 'MSE' designation corresponds to the 10-lead MSOP package type required for the design.

Selection Notes

Select this part when a quad DAC configuration is needed with high accuracy and automotive temperature stability. Ensure the system supply voltage remains within the 4.5V to 5.5V range required for the H-grade full-scale output.

Part Context

This component belongs to the LTC2635 family of quad DACs. The CMSE variant specifically denotes the commercial temperature grade logic compatibility but automotive operating range, the MSE package style, and the H-grade internal reference specification.

Replacement Considerations

Other members of the LTC2635 family, such as the LTC2635HMSE12 or LTC2635HZ12, offer similar electrical characteristics but differ in power-on reset behavior or reference voltage options.
