LTC2634HUD-LMI8#TRPBF

Overview

The LTC2634HUD-LMI8#TRPBF is a quad 8-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 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 a maximum integral nonlinearity error of ±0.5 LSB. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

Quad 8-bit resolution with ±0.5 LSB maximum INL
Integrated 2.5V full-scale precision reference (10ppm/°C)
Automotive grade (-40°C to 125°C) with AEC-Q100 qualification
Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the H-grade designation corresponds to the automotive temperature range of -40°C to 125°C. Ensure the LMI power-on reset configuration matches system requirements for mid-scale initialization in internal reference mode.

Selection Notes

Select this part when a quad DAC with 8-bit resolution and high accuracy is required for automotive applications. The 2.5V full-scale output suits systems needing lower voltage swings compared to the 4.096V variant. Verify that the 4.5V minimum supply voltage aligns with the system power architecture, as the L-series supports lower voltages down to 2.7V.

Part Context

This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The HUD package code specifies the 16-lead QFN form factor. The LMI suffix defines the power-on reset behavior as mid-scale in internal reference mode, distinguishing it from zero-scale or external reference reset options.
