ADI AD5700 Low Power HART Modem

The AD5700 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 integrates all of the necessary filtering, signal detection, modulating, demodulating and signal generation functions, thus requiring few external components. The maximum supply current consumption is 115µA, making the AD5700 an optimal choice for low power loop-powered applications. Transmit waveforms are phase continuous 1200 Hz and 2200 Hz sinusoids. The AD5700 contain accurate carrier detect circuitry and use a standard UART interface.
