The AD5700-1 is a monolithic solution designed to be used as a HART FSK half-duplex modem that meets HART® physical layer requirements. The device integrates all necessary filtering, signal detection, modulation, demodulation, and signal generation, requiring minimal external components. The integrated 0.5% precision oscillator saves board space, making it ideal for line-powered applications in master and slave configurations. The oscillator consumes a maximum supply of 285 μA, making the AD5700-1 an ideal complete low power solution for implementing each channel of HART I/O. The transmit waveforms are phase continuous 1200 Hz and 2200 Hz sine waves.
AD5700-1Includes precision carrier detection circuitry and adopts standard UART interface.
