LTC2634HUD-LMI12#TRPBF

Overview

The LTC2634HUD-LMI12#TRPBF is a quad 12-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 includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 125°C automotive temperature range, and communicates via a 50MHz SPI/MICROWIRE compatible interface. This specific part number indicates a tape and reel packaging format.

Feature Summary

• Quad 12-bit resolution with ±2.5 LSB maximum integral nonlinearity error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Automotive grade qualification (AEC-Q100) for -40°C to 125°C operation
• Power-on reset configured to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify that the #TRPBF suffix confirms the 2,500-unit tape and reel packaging configuration. Ensure the H-grade designation matches the required -40°C to 125°C operating temperature range for the target application environment.

Selection Notes

Select this component when a quad-channel DAC with high accuracy and automotive reliability is required. The LMI12 suffix specifies the mid-scale power-on reset behavior in internal reference mode; choose alternative suffixes if zero-scale reset or external reference operation is needed.

Part Context

This part belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The HUD package denotes the 16-lead QFN form factor, while the H suffix identifies the automotive temperature grade and 4.096V internal reference capability.
