Overview
The LTC2635HMSE-LZ8#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 with a full-scale output of 4.096V 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 automotive temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes.
Feature Summary
- Quad 10-bit DACs with integrated 4.096V full-scale reference
- Automotive temperature grade (–40°C to 125°C)
- Rail-to-rail output buffers with low crosstalk (3nV•s)
- Power-on reset options including zero-scale or high-impedance states
Applications
- Process control and industrial automation
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific suffix configuration against the manufacturer's ordering guide to confirm power-on reset behavior and package type. Ensure the design supports the required 4.5V to 5.5V supply voltage range for the H-grade variant. Confirm that the I²C bus pull-up resistors are correctly sized for the desired clock speed.
Selection Notes
Select this part when four independent 10-bit outputs are required in a compact MSOP footprint. The H-grade designation ensures operation at higher supply voltages (up to 5.5V) compared to the L-grade. Verify that the internal reference accuracy meets system requirements or consider external reference modes if different full-scale ranges are needed.
Part Context
This component belongs to the LTC2635 family, which offers 12-, 10-, and 8-bit resolutions. The HMSE suffix indicates the Automotive temperature grade and 10-lead MSOP package. Other variants include QFN packages and different power-on reset configurations such as mid-scale or high-impedance initialization.
Replacement Considerations
Direct substitutes within the same family include LTC2635CMSE-HZ8#TRPBF for commercial temperature range or LTC2635HMSE-HMI8#TRPBF for mid-scale reset behavior. Cross-family replacements require verification of pin compatibility and electrical specifications.
