LTC2636HDE-HMI10#TRPBF

Overview

The LTC2636HDE-HMI10#TRPBF 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 serial interface. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Octal architecture with 8 independent 10-bit DAC channels
• Integrated 10ppm/°C reference providing 4.096V full-scale output
• Automotive grade operation from –40°C to 125°C
• Rail-to-rail output buffers with ultralow crosstalk (<2.4nV•s)

Applications

• Process control and industrial automation systems
• Automatic test equipment requiring multi-channel precision
• Portable equipment with strict power constraints

Procurement Notes

Verify the H-grade designation confirms the –40°C to 125°C operating range and 4.5V minimum supply requirement. Confirm the DE suffix indicates the 14-lead DFN package and MI suffix specifies mid-scale power-on reset behavior. Ensure compatibility with 4.5V to 5.5V system voltages before integration.

Selection Notes

Select this part for applications requiring eight synchronized analog outputs with high accuracy. The H-grade variant is necessary for environments exceeding 85°C. The 10-bit resolution balances cost and performance for general-purpose control loops where 12-bit precision is not required.

Part Context

This component belongs to the LTC2636 family of octal DACs. The specific suffixes define its electrical characteristics: H denotes the automotive temperature range and 4.096V reference, DE indicates the 14-lead DFN package, and MI sets the power-on reset state to mid-scale.

Replacement Considerations

LTC2636HDE-LMI10#TRPBF offers identical specifications except for zero-scale power-on reset instead of mid-scale.
