Overview
The LTC2631HTS8-LM8#TRMPBF is an 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc., housed in an 8-lead TSOT-23 package. It features a high-accuracy internal reference with a full-scale output of 4.096V, requiring a supply voltage between 4.5V and 5.5V. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature. It utilizes a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. A power-on reset circuit initializes the output to mid-scale upon power-up. The part operates within a temperature range of –40°C to 125°C.
Feature Summary
- 8-Bit Resolution with 4.096V Full-Scale Output
- Integrated 10ppm/°C Reference for H-Grade
- I²C Interface with 400kHz Clock Rate Support
- Power-On Reset to Mid-Scale Configuration
Applications
- Process Control and Industrial Automation
- Portable Battery-Powered Equipment
- Automotive Systems
- Optical Networking
Procurement Notes
Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging option. Confirm the H-grade designation ensures operation across the extended automotive temperature range of –40°C to 125°C. Ensure the supply voltage meets the minimum 4.5V requirement for the 4.096V full-scale configuration.
Selection Notes
Select this model when an 8-bit resolution is sufficient for the application, reducing cost compared to 10 or 12-bit variants. The H-grade is required for environments exceeding 85°C. The LM suffix specifies a mid-scale power-on reset state; choose LZ if zero-scale initialization is needed. Verify that the system supply can maintain at least 4.5V for proper operation.
Part Context
This component belongs to the LTC2631 family of single-channel DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset behavior (mid-scale or zero-scale). The HTS8 package denotes the 8-lead ThinSOT form factor suitable for space-constrained designs.
Replacement Considerations
Direct pin-compatible substitutes include other LTC2631 variants such as LTC2631HTS8-LZ8#TRMPBF (zero-scale reset) or LTC2631HTS8-HM8#TRMPBF (if available in different grading). Cross-model replacements require verification of I²C addressability and register compatibility.
