PRODUCTION DATA.
The DAC8742H family of devices integrates modem functionality for several largely used Industrial protocols: Highway Addressable Remote Transducer (HART), FOUNDATION Fieldbus (FF), and PROFIBUS (PA). The different modes are set via the CLK_CFGx pins of the device that allow the device to either enter HART or PAFF mode. In HART mode, a 1200-/2200-Hz HART FSK Signal is modulated and demodulated, while the PAFF mode communicates via a 31.25 Kbit/s Manchester coded/encoded signal. The small package sizes, wide temperature range and low quiescent current make this device an ideal candidate for applications in Industrial Process Control and Automation.
