LTC2635CUD-HMI10#TRPBF

Overview

The LTC2635CUD-HMI10#TRPBF is a quad 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated precision reference with a full-scale output of 4.096V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It includes rail-to-rail output buffers, double-buffered data latches, and guarantees monotonicity over the operating temperature range. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. The part incorporates a power-on reset circuit configured to reset outputs to mid-scale in internal reference mode.

Feature Summary

• Quad 10-Bit Resolution with Integrated 4.096V Reference
• I²C Interface with Standard and Fast Mode Support
• Power-On Reset to Mid-Scale (Internal Reference)
• Rail-to-Rail Output Buffers Guaranteed Monotonic

Applications

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

Procurement Notes

Verify the ordering suffix #TRPBF indicates lead-free construction and tape-and-reel packaging containing 2,500 pieces. Confirm the C-grade designation aligns with commercial temperature requirements (0°C to 70°C). Ensure the H-grade specification for the 4.5V to 5.5V supply range is compatible with the system power architecture.

Selection Notes

Select this component when a quad-channel DAC with high accuracy and low drift is required. The H-grade variant supports a 4.096V full-scale output suitable for 5V systems. The MI suffix ensures outputs initialize to mid-scale upon power-up, which may be necessary for specific safety or initialization protocols in the target application.

Part Context

This part belongs to the LTC2635 family, which includes 8-bit, 10-bit, and 12-bit variants. The 'H' suffix denotes the 4.096V full-scale version requiring a minimum 4.5V supply, while 'L' variants offer 2.5V full-scale with a lower 2.7V minimum supply. The 'UD' package code specifies the 16-lead QFN form factor used in this part number.

Replacement Considerations

Compatible substitutes within the same family include LTC2635CUD-LMI10#TRPBF for 2.5V applications or LTC2635CUD-HZ10#TRPBF if zero-scale power-on reset is preferred. Cross-package replacements such as the MSE (MSOP) versions are available but require pinout verification.
