LTC2635HUD-LMO8#TRPBF

Overview

The LTC2635HUD-LMO8#TRPBF is a quad 8-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 operates from 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 low noise of 0.75mVP-P. Communication is handled via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. The power-on reset circuit configures outputs to a high-impedance state upon initialization.

Feature Summary

Quad 8-Bit DACs with Integrated Precision Reference
4.096V Full-Scale Output (LTC2635-H)
Automotive Temperature Range (–40°C to 125°C)
Power-On Reset to High-Impedance State

Applications

Process Control and Industrial Automation
Power Supply Margining
Automotive Systems

Procurement Notes

Verify the specific ordering suffix LMO against the manufacturer's documentation to confirm the power-on reset behavior. Ensure the application environment supports the required 4.5V to 5.5V supply voltage for the H-grade variant. Confirm that the 16-pin QFN package requirements align with the PCB layout specifications.

Selection Notes

Select this part when four independent 8-bit channels are required in an automotive or industrial setting. The H-grade designation ensures operation within the extended temperature range and provides a 4.096V full-scale output. The LMO suffix is critical if a high-impedance output state is required immediately after power-up to prevent unintended signal driving.

Part Context

This component belongs to the LTC2635 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The HUD prefix indicates the Automotive temperature grade and 16-pin QFN package. The LMO suffix specifically defines the power-on reset function as resetting to mid-scale internally while placing all DAC outputs in a high-impedance state.
