Demonstration circuit by ADI for a loop powered HART

Analog Devices has introduced the CN0267 demonstration circuit for a loop powered HART (Highway Addressable Remote Transducer) enabled smart transmitter, for industrial applications that need to operate within a set 3.5-mA power budget. This field instrument circuit is tested and verified by ADI.

This circuit has been compliance tested, verified and registered as an approved HART solution by the HART Communication Foundation. The 7-cm by 2.3-cm CN0267 PCB demonstrates a direct sensor interface, microprocessor and two-way HART communication over a 4- 20-mA loop.

CN0267 combines three of ADIís lowest power, high performance components, optimized for field instrument designs;

The ADuCM360, a low power, fully integrated, 3.9-kSPS, 24-bit data acquisition system-on-a-chip incorporating dual, sigma-delta A/D converters, a 32-bit ARM CortexTM M3 MCU, and flash/EE memory.
The AD5421, is a complete, loop powered, 16-bit, 4-mA to 20-mA DAC that incorporates a programmable voltage regulator used to power the demonstration board.
The AD5700 is a complete HART modem IC, consuming 38 percent less power and supporting a greater than 75 percent saving in board area over alternative products.
