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 ADM8323/ADM8324 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems. An on-chip watchdog timer checks for activity within a preset timeout window. A reset signal can also be asserted by an external push-button switch through a manual reset input. The RESET output is either push-pull (ADM8323) or open-drain (ADM8324).

A watchdog failure results in a low output on the RESET pin. A failure can be triggered either by a fast watchdog error (watchdog pulses too close together) or by a slow watchdog error (no watchdog pulse within the timeout period). This effectively gives a window to observe the watchdog pulse. The watchdog timeout is measured from the last falling edge of the watchdog input (WDI). There are eight different watchdog windows available.
