LTC2636HMS-HMX10#TRPBF

Overview

The LTC2636HMS-HMX10#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 utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. It includes double-buffered data latches, rail-to-rail output buffers, and guaranteed monotonicity over the –40°C to 125°C automotive temperature range. Power-on reset defaults to mid-scale in external reference mode.

Feature Summary

• Octal 10-Bit Resolution with Rail-to-Rail Output Buffers
• Integrated 4.096V Precision Reference (10ppm/°C Drift)
• Automotive Temperature Grade (–40°C to 125°C)
• SPI/MICROWIRE Interface with Hardware Clear (CLR) and LDAC Pins

Applications

• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Optical Networking

Procurement Notes

Verify the H-grade automotive rating and MSOP-16 package configuration. Confirm the HMX suffix indicates power-on reset to mid-scale in external reference mode. Ensure the #TRPBF suffix matches the required tape and reel quantity for production integration.

Selection Notes

Select this part for applications requiring eight independent channels with high accuracy and automotive reliability. The 4.096V internal reference simplifies design by eliminating external components. Verify that the 4.5V minimum supply voltage aligns with system power rails.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8-, 10-, or 12-bit), full-scale voltage (2.5V or 4.096V), and temperature grade (Commercial, Industrial, or Automotive). The MSOP package provides hardware control pins not available in the DFN version.
