LTC2636HDE-HMI12#TRPBF

Overview

The LTC2636HDE-HMI12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 4.096V full-scale reference with a temperature coefficient of 10ppm/°C. The device operates on a single 4.5V to 5.5V supply and utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to mid-scale in internal reference mode, and rail-to-rail output buffers. The component is housed in a 14-lead DFN package and supports automotive temperature ranges.

Feature Summary

• Octal 12-bit resolution with guaranteed monotonicity over –40°C to 125°C
• Integrated 4.096V reference with ±10ppm/°C drift
• SPI/MICROWIRE compatible 3-wire serial interface operating at 50MHz
• Power-on reset to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel packaging format containing 2500 pieces. Confirm that the H-grade designation aligns with the required automotive temperature range of –40°C to 125°C for the target application environment.

Selection Notes

Select this part when eight independent 12-bit channels are required with high accuracy and low drift. Ensure the system supply voltage remains within the 4.5V to 5.5V range specified for the H-series. Consider the external reference option if a different full-scale voltage is needed, though this specific model uses the internal 4.096V reference.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8, 10, or 12 bits), package type (DFN or MSOP), and temperature grade (C, I, or H). The HDE suffix specifically denotes the 14-lead DFN package and Automotive temperature grade.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the octal configuration, 12-bit resolution, and automotive temperature specifications.
