The AD5700 HART modem IC enables HART connectivity in process control applications such as smart sensors and factory automation equipment and is fully compliant with the HART Communication Protocol.
The single-chip device is compliance registered with the HART Communication Foundation and the company says that it requires the lowest power in the industry. It integrates in a single chip all the necessary filtering, signal detection, modulation, demodulation and signal generation functions needed to achieve HART connectivity, so designs require few external support components, providing a greater than 75% saving in board area over competing products. In analog I/O modules, the reduction in board space made possible enables the per-channel inclusion of HART without the need to increase system form factor. The device consumes 38% less power than alternative solutions, and this power savings enables system engineers designing smart sensor applications to reduce their power budgets, lower system costs and optimize board space to accommodate supplementary functionality.
