Complete HART modem IC targets process control applications
March 05, 2012 // Julien Happich
Analog Devices has introduced a complete HART (Highway Addressable Remote Transducer) modem IC (integrated circuit) that enables HART connectivity in process control applications such as smart sensors and factory automation equipment.
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 AD5700 HART modem IC is Analog Devices' first complete IC offering for HART Communication and is compliance registered with the HART Communication Foundation.
The AD5700 HART modem IC accurately encodes and decodes HART communication signals in noisy, harsh industrial environments, ensuring a reliable communication interface. According to the manufacturer, the chip requires 60 percent less external support components and is the first to incorporate an internal low-power 0.5 percent accurate oscillator (for the AD5700-1 variant) , internal receive filtering and an internally buffered HART output, providing a greater than 75 percent saving in board area over competing products. In analog I/O modules, the reduction in board space made possible by the AD5700 modem IC enables the per channel inclusion of HART without the need to increase system form factor. The device consumes 38 percent 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. Specified for a wide industrial temperature range of –40 to +125°C, the device is delivered in a 4×4mm LFCSP (lead frame chip scale package).
