Overview
The LTC2634IUD-HMX10#PBF is a quad 10-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V 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 85°C industrial temperature range, and communicates via a 50MHz SPI/MICROWIRE compatible 3-wire serial interface. Upon power-up, the outputs reset to mid-scale in external reference mode.
Feature Summary
- Quad 10-bit DACs 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
Procurement Notes
Verify the package type matches the design requirements, as this model uses a 16-lead QFN. Confirm that the operating environment stays within the specified -40°C to 85°C industrial temperature range. Ensure the system power supply remains between 4.5V and 5.5V for proper operation of the internal reference.
Selection Notes
Select this component when a quad DAC configuration with high accuracy and low noise is required. The H suffix indicates a 4.096V full-scale output suitable for applications needing higher dynamic range than the 2.5V L-series. The MX suffix specifies the mid-scale reset behavior in external reference mode, which may be necessary for specific system initialization sequences.
Part Context
This part belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The I-grade designation identifies it as the industrial temperature variant, distinct from the commercial C-grade and automotive H-grade options available within the same product line.
Replacement Considerations
Direct replacements include other LTC2634 variants with matching resolution and package, such as LTC2634IUD-LMX10#PBF or LTC2634IUD-HMI10#PBF, depending on the required power-on reset behavior and reference mode.
