DAC8740HRGER Description

Short technical summary and product information.

The Texas Instruments DAC8740HRGER is a low-power modem IC designed for industrial process control and automation applications. It offers compatibility with HART, FOUNDATION Fieldbus H1, and PROFIBUS PA communication standards.

 

This specialized interface IC features a UART digital interface and supports communication speeds up to 31.25 kbit/s using Manchester-coded bus powered (MBP). It includes an integrated RX demodulator and band-pass filter, along with flexible clocking options via an internal oscillator or external crystal. The device operates over a wide temperature range of -55°C to 125°C.

 

The DAC8740HRGER is housed in a compact 4mm x 4mm 24-VQFN package, suitable for surface mount applications. Its low quiescent current of 180 µA maximum makes it an energy-efficient choice for industrial systems. The integrated 1.5-V reference further simplifies design.

 

Key features include HART-compliant physical layer modem capabilities, FOUNDATION Fieldbus H1 controller and medium attachment unit (MAU), and PROFIBUS PA compatibility. Reliability is enhanced with CRC bit error checking.
