Overview
The AD5700BCPZ-R5, produced by Analog Devices Inc., is a single-chip solution designed to operate as a HART® FSK half-duplex modem. It complies with the HART physical layer requirements, integrating all necessary functions such as filtering, signal detection, modulation, demodulation, and signal generation. This integration minimizes the need for external components, making it ideal for low-power loop-powered applications in both HART field instrument and master configurations.
