LTC2634IUD-HMI10#TRPBF

Overview

The LTC2634IUD-HMI10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 85°C industrial temperature range, and communicates via a 50MHz SPI/MICROWIRE compatible 3-wire serial interface. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum INL error
• Integrated 10ppm/°C precision reference yielding 2.5V full-scale output
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV·s)
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the #TRPBF suffix indicates a tape and reel packaging format containing 2,500 pieces. Confirm the I-grade designation corresponds to the specified -40°C to 85°C operating temperature range for this specific part number.

Selection Notes

Select this model for applications requiring four independent 10-bit channels with a 2.5V internal reference limit. Ensure the system power supply remains within the 2.7V to 5.5V range. Consider the H-grade variant if operation up to 125°C is required.

Part Context

This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in 16-lead QFN and 10-lead MSOP packages. The IUD suffix identifies the Industrial temperature grade and 16-lead QFN package configuration.
