DAC8741HRGET

Specialized Overview

The DAC8741HRGET is a specialized interface integrated circuit manufactured by Texas Instruments, designed for industrial process control applications. It functions as a HART modem and supports FOUNDATION Fieldbus and PROFIBUS PA protocols. The device operates within a supply voltage range of 2.7 V to 5.5 V and features an SPI digital interface. It is housed in a 24-VQFN package with dimensions of 4x4 mm. The component is rated for operation between -55°C and +125°C and carries a Moisture Sensitivity Level (MSL) rating of 2, allowing for one year of shelf life under standard conditions.

Specialized Feature Summary

• Integrates physical layer modulation compatible with HART, FOUNDATION Fieldbus, and PROFIBUS PA standards for industrial communication.
• Provides a low-power solution suitable for two-wire field sensor-transmitters and process automation environments.
• Includes an internal 1.5V voltage reference and supports flexible digital connectivity via SPI or UART interfaces.

Specialized Applications

• HART modem implementation in industrial instrumentation
• FOUNDATION Fieldbus H1 controller integration
• PROFIBUS PA device interfacing
• Two-wire field sensor-transmitter signal conditioning

Specialized Procurement Notes

Verify the specific suffix 'GET' against the manufacturer's official documentation to confirm packaging configuration, such as tape-and-reel specifications. Ensure that the ordering information matches the exact part number required for your bill of materials, as distributor listings may vary in stock availability and lead times. Cross-reference the RoHS status and MSL rating with current regulatory requirements before finalizing procurement orders.

Specialized Selection Notes

Select this component when designing systems requiring certified compatibility with HART, FOUNDATION Fieldbus, or PROFIBUS PA protocols. The DAC8741HRGET is appropriate for applications needing a compact 24-pin VQFN footprint and wide temperature tolerance. Consider the integrated voltage reference and low static current characteristics if power efficiency is a primary design constraint for battery-operated or energy-harvesting field devices.

Specialized Part Context

This part belongs to the DAC874xH series from Texas Instruments, which includes compatible models like the DAC8740H and DAC8742H. These components share similar functional architectures for industrial fieldbus applications. Evaluation modules, such as the DAC8742HEVM, are available to assist in the development and testing of designs utilizing this family of specialized interface ICs.

Specialized Replacement Considerations

The DAC8740H and DAC8742H are documented as compatible members of the same product family. Verify pinout and feature parity with the official datasheet before substituting these parts in existing designs to ensure protocol compliance and electrical compatibility.
