Overview
The LTC2634HMSE-LMX10#PBF is a quad 10-bit voltage output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead MSOP package. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single supply voltage ranging from 4.5V to 5.5V. The device includes rail-to-rail output buffers and is guaranteed monotonic over the -40°C to 125°C temperature range. Communication is handled via an SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz. Power-on reset defaults to mid-scale in external 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 external reference mode
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix #PBF indicates lead-free construction. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the H grade matches the required -40°C to 125°C automotive temperature range. Check that the LMX suffix aligns with the mid-scale power-on reset requirement for external reference configurations.
Selection Notes
Select this part when four independent 10-bit DAC channels are required in a compact surface-mount package. The 4.096V internal reference suits applications needing precise scaling without external components. The H-grade temperature rating is necessary for environments exceeding 85°C. Verify that the 4.5V minimum supply voltage is compatible with the system power rails.
Part Context
This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The HMSE variant specifically denotes the H-grade temperature performance, MSOP packaging, and mid-scale reset in external reference mode. It shares architectural similarities with other members like the LTC2634HUD series but differs in pin count and package type.
Replacement Considerations
Direct substitutes within the same family include LTC2634IMSE-HMX10#PBF for industrial temperature range or LTC2634HMX10#PBF if package verification is needed. Cross-package replacements require schematic review due to pinout differences between MSOP and QFN variants.
