Overview
The LTC2634HMSE-HMI12#TRPBF is a quad 12-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 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 a maximum integral nonlinearity error of ±2.5 LSB. Communication is handled via a 50MHz SPI/MICROWIRE compatible 3-wire serial interface.
Feature Summary
- Quad 12-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
Procurement Notes
Verify the specific ordering suffix #TRPBF indicates a tape and reel packaging configuration containing 2,500 pieces. Confirm that the H-grade designation corresponds to the automotive temperature range of -40°C to 125°C as specified in the manufacturer's documentation.
Selection Notes
Select this part for applications requiring four independent 12-bit channels with high accuracy and low drift. Ensure the system power supply remains within the 4.5V to 5.5V range required for the H-version full-scale output. Consider the MSOP package constraints if board space is limited compared to the QFN alternative.
Part Context
This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The HMSE suffix identifies the specific combination of H-grade temperature rating, MSOP package type, and mid-scale internal reference power-on reset behavior.
Replacement Considerations
Direct substitutes include other members of the LTC2634 family such as the LTC2634HMS-HMI12#TRPBF or LTC2634HUD-HMI12#TRPBF, provided the package type and temperature grade requirements are met.
