LTC2636HMS-HMI10#TRPBF

Overview

The LTC2636HMS-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 double-buffered data latches. Communication occurs via a 50MHz SPI-compatible 3-wire serial interface. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

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

Applications

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

Procurement Notes

Verify the H-grade designation for the –40°C to 125°C automotive temperature range and the MS package type for the 16-lead MSOP housing. Confirm the TRPBF suffix indicates tape-and-reel packaging with lead-free compliance. Ensure the HMI10 code matches the required 4.096V full-scale output and mid-scale power-on reset behavior.

Selection Notes

Select this part when eight independent DAC channels are required in a compact footprint. The H-grade variant is necessary for high-temperature automotive environments. The HMI10 configuration provides a fixed 4.096V span using the internal reference, eliminating the need for external components while ensuring mid-scale initialization upon power-up.

Part Context

This component belongs to the LTC2636 family of octal DACs, which also offers 8-bit and 12-bit resolutions. Variants include the L-series for 2.7V–5.5V supplies and C/I grades for commercial/industrial ranges. The MSOP package distinguishes it from the DFN version by providing dedicated CLR and LDAC pins.
