LTC2632HTS8-LI10#TRMPBF

Overview

The LTC2632HTS8-LI10#TRMPBF is a dual 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. It includes power-on reset functionality that sets outputs to mid-scale in internal reference mode upon startup.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V full-scale reference
• Rail-to-rail output buffers with guaranteed monotonicity
• 3-wire serial interface with 50MHz clock capability
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration as defined in the manufacturer's documentation. Confirm the H-grade automotive temperature range (-40°C to 125°C) matches the application requirements. Ensure the LI10 designation for mid-scale reset and 10-bit resolution aligns with system initialization needs.

Selection Notes

Select this component when a dual-channel DAC with an integrated 2.5V reference is required in a compact TSOT-23 package. The 10-bit resolution offers a balance between accuracy and data throughput. The H-grade variant is suitable for automotive environments requiring operation from -40°C to 125°C. Consider the external reference option if a different full-scale voltage is needed.

Part Context

This part belongs to the LTC2632 family of dual DACs, which also includes 12-bit and 8-bit variants. The 'H' prefix denotes the automotive temperature grade, while 'LI10' specifies the 10-bit resolution and mid-scale power-on reset behavior in internal reference mode. Other family members include the LTC2632L series for commercial temperatures and different reset configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing within the LTC2632 family may be possible by adjusting resolution or temperature grade requirements, but direct pin-for-pin replacements with other manufacturers require separate verification.
