The AD5700/AD5700-1 are single-chip solutions, designed and specified to operate as a HART® FSK half-duplex modem, complying with the HART physical layer requirements. The AD5700/AD5700-1 integrate all of the necessary filtering, signal detection, modulating, demodulating and signal generation functions, thus requiring few external components. The 0.5% precision internal oscillator on the AD5700-1 greatly reduces the board space requirements, making it ideal for line-powered applications in both master and slave configurations. The maximum supply current consumption is 115µA, making theAD5700/AD5700-1 an optimal choice for low power loop-powered applications. Transmit waveforms are phase continuous 1200 Hz and 2200 Hz sinusoids. The AD5700/AD5700-1 contain accurate carrier detect circuitry and use a standard UART interface.

Applications

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

Product Detail

Both the AD5700 and the AD5700-1 products can be evaluated using the EVAL-AD5700-1EBZ Evaluation board. If evaluating the AD5700 product, simply disable the internal oscillator (i.e. configure the part to use either a CMOS clock or a crystal oscillator). No SDP board is required for this Evaluation board.
