Overview
The LTC2636HDE-LMX10#TRPBF is an octal 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 125°C automotive temperature range, and communicates via a 3-wire SPI/MICROWIRE interface. It incorporates a power-on reset circuit that sets outputs to mid-scale in external reference mode.
Feature Summary
- Octal architecture with 8 independent 10-bit DAC channels
- Integrated 10ppm/°C reference providing 4.096V full-scale output
- Automotive grade operation from –40°C to 125°C
- Power-on reset to mid-scale in external reference mode
Applications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix #TRPBF indicates a tape and reel packaging configuration containing 2500 pieces. Confirm the DE package designation corresponds to the 14-lead DFN form factor. Ensure the H-grade specification matches the required 4.5V to 5.5V supply voltage range for the application.
Selection Notes
Select this part when eight simultaneous voltage outputs are required with high accuracy. The H-series variant is necessary for applications demanding a 4.096V full-scale range. The LMX suffix specifies the mid-scale reset behavior suitable for external reference designs. Verify that the 4.5V minimum supply voltage aligns with the system power rails.
Part Context
This component belongs to the LTC2636 family of octal DACs. The HDE-LMX10 designation specifically identifies the 10-bit resolution, 4.096V full-scale capability, 14-lead DFN package, and mid-scale reset in external reference mode. Other variants in the series offer different resolutions, package types, and reset behaviors.
Replacement Considerations
Direct substitutes within the same family include LTC2636HDE-HMX10#TRPBF (different reset behavior) or LTC2636HDE-LMX10#TRPBF (identical specifications). Cross-package replacements like the MSOP version require pinout verification.
