The AD5700-1ACPZ-RL7 is a Low Power HART Modem with precision internal oscillator for low power loop-powered applications. It integrates 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 modem greatly reduces the board space requirements, making it ideal for line-powered applications in both master and slave configurations. Transmit waveforms are phase continuous 1200Hz and 2200Hz sinusoids. It contains accurate carrier detect circuitry and use a standard UART interface.
