LTC2631CTS8-HM10#TRPBF

Overview

The LTC2631CTS8-HM10#TRPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an integrated precision reference with a full-scale output of 4.096V and operates from a 4.5V to 5.5V supply. The device utilizes a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical settling time of 4.2µs at ±1 LSB for 10-bit resolution, and a power-on reset function that defaults the output to mid-scale. The component is housed in an 8-lead TSOT-23 package.

Feature Summary

• 10-Bit Resolution with ±1 LSB Maximum INL Error
• Integrated 4.096V Reference with 10ppm/°C Temperature Coefficient
• I²C Interface Supporting 400kHz Fast Mode
• Power-On Reset to Mid-Scale Output

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging format. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the HM10 suffix correctly identifies the 10-bit resolution and mid-scale power-on reset configuration before procurement.

Selection Notes

Select this part when a 4.096V full-scale output is required with a minimum supply voltage of 4.5V. The mid-scale power-on reset option is suitable for applications where a zero-volt startup is not mandatory. Verify that the system I²C bus supports the 400kHz clock rate if fast mode operation is desired. Consider the external reference capability if a different full-scale voltage is needed.

Part Context

This component belongs to the LTC2631 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common 8-lead TSOT-23 package and I²C interface architecture. Variations within the family differ primarily in resolution accuracy, internal reference voltage (2.5V or 4.096V), and power-on reset behavior (zero or mid-scale).

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult Analog Devices marketing for information on alternative components or non-standard lead-based finish parts.
