LTC2631HTS8-LZ8#TRMPBF

Overview

The LTC2631HTS8-LZ8#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 supports a 2-wire I²C interface operating at standard (100kHz) and fast (400kHz) modes. It includes a power-on reset circuit configured to clear the output to zero-scale upon power-up. The part operates within an automotive temperature range of –40°C to 125°C.

Feature Summary

• 8-Bit Resolution with Guaranteed Monotonicity
• 4.096V Full-Scale Output with Internal Reference
• I²C Interface with Zero-Scale Power-On Reset
• Automotive Temperature Grade (–40°C to 125°C)

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging option. Confirm that the H-grade designation matches the required 4.5V to 5.5V supply range and –40°C to 125°C operating temperature for the target application environment.

Selection Notes

Select this part when an 8-bit resolution is sufficient for the application's accuracy requirements. The H-grade variant is necessary for automotive or high-temperature environments. Ensure the system supply voltage remains within the 4.5V to 5.5V range, as lower voltages will not support the 4.096V full-scale output specification.

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 temperature grade (C, I, or H). The LZ suffix specifically denotes the zero-scale power-on reset configuration.
