LTC2636CMS-HMI10#PBF

Overview

The LTC2636CMS-HMI10#PBF is an octal, 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 on a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers and guarantees monotonicity over the specified temperature range. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. This specific variant provides a power-on reset to mid-scale in external reference mode and is housed in a 16-lead MSOP package.

Feature Summary

• Octal architecture with 8 independent 10-bit DAC channels
• Integrated 10ppm/°C precision reference yielding 4.096V full-scale output
• Rail-to-rail output buffers ensuring guaranteed monotonic operation
• Power-on reset configured to mid-scale for external reference mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive applications
• Optical networking

Procurement Notes

Verify the component matches the exact part number LTC2636CMS-HMI10#PBF. Confirm the manufacturer is Analog Devices Inc. Ensure the package type is 16-lead MSOP. Check that the internal reference setting corresponds to the 4.096V full-scale specification required for your design.

Selection Notes

Select this part when eight simultaneous analog outputs are required with high accuracy. The 4.096V full-scale range suits 5V logic systems. The H-grade temperature rating (-40°C to 125°C) is necessary for automotive or harsh industrial environments. Choose this specific suffix if mid-scale initialization in external reference mode is required upon power-up.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), temperature grade (C, I, or H), and package type (DFN or MSOP). The CMS designation indicates the commercial temperature grade, while HMI10 specifies the 10-bit resolution and mid-scale reset behavior.
