Texas Instruments XDAC8740HRGET

The DAC8740H, DAC8741H, and DAC8742H are HART®, FOUNDATION Fieldbus™, and PROFIBUS PA compliant low power modems designed for industrial process control and industrial automation applications.

In HART mode, the DAC874xH integrates all of the required circuitry to operate as half-duplex HART physical layer modems, in either slave or master configurations with minimal external components for filtering. In FOUNDATION Fieldbus mode, the DAC874xH integrates all of the required circuitry to operate as half-duplex FOUNDATION Fieldbus compliant H1 Controllers and MAUs.

The HART, FOUNDATION Fieldbus, or PROFIBUS PA, data stream can be transferred from the microcontroller through either a UART interface or an integrated FIFO accessed by a SPI interface. The SPI interface includes an SDO pin for daisy-chain support, various interrupts, and other extended features.

The devices operate from a supply of 2.7V to 5.5V while consuming only 200 uA, making them an excellent choice for loop-powered or 2-wire applications. They operate from –55°C to 125°C and are available in 24-lead VQFN and 32-lead TQFP packages.
