LTC2633CTS8-LI8#TRMPBF

Overview

The LTC2633CTS8-LI8#TRMPBF is a dual-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision internal reference with a temperature coefficient of 10ppm/°C and operates on a single 2.7V to 5.5V supply. The device features rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Dual 8-bit DACs with integrated 10ppm/°C precision reference
• Rail-to-rail output buffers with guaranteed monotonicity
• Automotive grade operation from –40°C to 125°C
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive systems

Procurement Notes

Verify the #TRMPBF suffix indicates a 500-unit tape and reel packaging configuration. Confirm that the 'C' temperature grade designation aligns with the specified automotive operating range of –40°C to 125°C for the target application environment.

Selection Notes

Select this part for applications requiring dual low-resolution channels with minimal external component count. Ensure the supply voltage remains within 2.7V to 5.5V. Consider the 8-bit resolution limits if higher precision is required, or verify that the mid-scale power-on reset behavior meets system initialization requirements.

Part Context

This component belongs to the LTC2633 family of dual I²C DACs. Variants differ by resolution (8-, 10-, or 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset options. The specific suffixes define the package type, temperature grade, and electrical accuracy class.
