Overview
The LTC2634HMSE-HMI10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference providing a 4.096V full-scale output 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 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 integrated 4.096V precision reference
- Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
- SPI/MICROWIRE compatible 3-wire serial interface up to 50MHz
- Power-on reset 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 the H-grade temperature rating (-40°C to 125°C) and MSE package type against design requirements. Confirm the HMI suffix indicates power-on reset to mid-scale in internal reference mode. Ensure the supply voltage remains within the 4.5V to 5.5V range for specified performance.
Selection Notes
Select this part for applications requiring four independent 10-bit outputs with high accuracy and low drift. The H-grade variant is suitable for automotive or harsh industrial environments. Compare settling time and noise specifications against system bandwidth requirements. Consider the external reference option if a different full-scale voltage is needed.
Part Context
This component belongs to the LTC2634 family of quad DACs, which also offers 8-bit and 12-bit resolutions. Variants include the LTC2634-L for 2.5V full-scale operation and the QFN package option. The HMSE designation specifically identifies the H-grade, 10-bit, MSOP package configuration.
Replacement Considerations
Direct substitutes within the same family include LTC2634IMSE-HMI10#PBF (tube packaging) or LTC2634HUD-HMI10#PBF (QFN package). Verify pin compatibility and thermal characteristics when switching between MSOP and QFN packages.
