Analog Devices has introduced the CN0267 demonstration circuit for a loop powered HART enabled smart transmitter. It is designed for industrial applications that need to operate within a set 3,5 mA power budget. This field instrument circuit demonstrates a complete low power, high precision signal chain solution with minimum area overhead, which has been tested and verified by ADI as part of its ‘Circuits From The Lab’ reference circuits initiative.
The circuit has been compliance tested, verified and registered as an approved HART solution by the HART Communication Foundation. This ensures that systems designed with these ADI devices will adhere to HART protocol requirements and that DEMO-AD5700D2Z is a proven, tested solution.
Combining the lowest-power components in their class, this solution enables system engineers to support increased system functionality, including the communication of diagnostics and additional measurement or calibration data. The 7 x 2,3 cm CN0267 PCB demonstrates a direct sensor interface, microprocessor and two-way HART communication over a 4–20 mA loop.
The CN0267 combines three of ADI’s lowest power, high performance components, optimised for field instrument designs. The ADuCM360 is a low power, fully integrated, 3,9 KSps, 24-bit data acquisition system-on-a-chip. It incorporates dual sigma-delta A/D converters, a 32-bit ARM Cortex M3 MCU and flash/EE memory. Using less than 1 mA of operating current, it claims to deliver more processing per mW of power than any other analog microcontroller within its class.
Consuming less than 300 μA of quiescent current, the AD5421 is a complete, loop powered, 16-bit, 4-20 mA DAC that incorporates a programmable voltage regulator used to power the demonstration board.
The AD5700 is a complete HART modem IC, claiming 38% less power consumption and 75% less board area than alternative products.
