Product Details

The AD5700 is a single-chip solution, designed and specified to operate as a HART® FSK half-duplex modem, comply­ing with the HART physical layer requirements. The AD5700 integrates all of the necessary filtering, signal detection, modulating, demodulating and signal generation functions, thus requiring few external components. The maxi­mum supply current consumption of 115 µA and the small 4mm x 4mm housing, makes the AD5700 an optimal choice for low power loop-powered applica­tions. Transmit waveforms are phase continuous 1200 Hz and 2200 Hz sinusoids. The AD5700 contains accurate carrier detect circuitry and uses a standard UART interface.

Applications
  • Field transmitters
  • HART multiplexers
  • PLC and DCS analog I/O modules
  • HART network connectivity
