The AD5700 is 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 is 115µA, making the AD5700 an optimal choice for lowpower loop-powered applications. Transmit waveforms are phase continuous 1200 Hz and 2200 Hz sinusoids. The AD5700 contains accurate carrier detect circuitry and use a standard UART interface. The AD5700 enables quick and easy deployment of a robust HART-compliant system.

This article provides you with a basic overview of the AD5700 HART Modem, including its pin descriptions, features and specifications, etc., to help you quickly understand what AD5700 is.
