The AD5700 HART (Highway Addressable Remote Transducer) modem IC enables HART connectivity in process control applications such as smart sensors and factory automation equipment. According to the company, the single-chip device requires the lowest power in the industry and is fully compliant with the HART Communication Protocol, which is the global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring systems.
The IC requires 60% less external components and is the first to incorporate an internal low-power 0.5% accurate oscillator, internal receive filtering and an internally buffered HART output, providing a greater than 75% saving in board area over competing products.
Additional features include: a receive mode supply current of 115 µA maximum, 8 kV HBM ESD rating, 2 to 5.5 V power supply, and a 1.71 to 5.5 V interface, Housed in a 4 x 4-mm LFCSP, the part operates from -40 to 125C.Also available is the AD5700-1, which is similar to the AD5700, but it includes an internal precision oscillator.
