LTC2636HDE-LMI10#PBF

Overview

The LTC2636HDE-LMI10#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, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. It incorporates a power-on reset circuit that sets outputs to mid-scale in internal reference mode.

Feature Summary

• Octal 10-Bit Resolution with Integrated 4.096V Reference
• Automotive Grade: –40°C to 125°C Operating Range
• Rail-to-Rail Output Buffers with Guaranteed Monotonicity
• Power-On Reset to Mid-Scale in Internal Reference Mode

Applications

• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific suffix 'LMI10' confirms the 10-bit resolution, mid-scale power-on reset behavior, and 4.096V full-scale output. Confirm the 'H' grade designation matches the required –40°C to 125°C automotive temperature specification for the application environment.

Selection Notes

Select this part when eight independent voltage outputs are required with high accuracy and automotive reliability. Ensure the system supply voltage supports the 4.5V to 5.5V operating range required by the H-grade variant. Consider the MSOP-16 package dimensions if board space is constrained.

Part Context

This component belongs to the LTC2636 family of octal DACs. The 'H' suffix denotes the automotive temperature grade, while 'DE' specifies the 14-lead DFN package. Other variants include different resolutions (8/12-bit), reset behaviors (Zero/Mid-scale), and packages (MSOP).
