AD5700 Datasheet PDF

●The AD5700BCPZ-R5 is a single-chip IC, designed and specified to operate as a HART® FSK Half-Duplex Modem, complying with the HART physical layer requirements. The device 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 device an optimal choice for low power loop-powered applications. The device contains accurate carrier detect circuitry and use a standard UART interface.
