LTC2631HTS8-HM10#TRMPBF

Overview

The LTC2631HTS8-HM10#TRMPBF is a single 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc., housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 4.096V and operates on a 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature, a bidirectional reference pin, and a 400kHz I2C interface. Power-on reset defaults to mid-scale, and the H-grade ensures operation from –40°C to 125°C.

Feature Summary

• 10-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V reference with 10ppm/°C drift
• 400kHz I2C serial interface
• Power-on reset to mid-scale

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems
• Optical networking

Procurement Notes

Verify the H-grade temperature rating (-40°C to 125°C) and the HM10 suffix indicating mid-scale reset and 10-bit resolution. Confirm the TRMPBF suffix denotes a 500-unit tape and reel packaging format. Ensure the 4.5V minimum supply requirement aligns with system power rails.

Selection Notes

Select this part for applications requiring a 4.096V full-scale range and mid-scale initialization upon power-up. The H-grade is necessary for automotive or high-temperature environments. For lower voltage operation (2.7V–5.5V), consider the L-grade variant instead.

Part Context

This component belongs to the LTC2631 family of single-channel DACs. Variants differ by resolution (8/10/12-bit), reset behavior (Z/M), and temperature grade (C/I/H). The HTS8 designation specifies the H-grade temperature range and TSOT-23 package.
