Signal Chain Solution for 4-mA to 20-mA HART Enabled Field Instrument Applications
26 March 2013 - 3:01PM
Business Wire
Analog Devices, Inc. (NASDAQ: ADI) introduced today 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 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 their Circuits
from the Lab™ reference circuits’ initiative.

This 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 communications of diagnostics and
additional measurement or calibration data. 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.
About the CN0267 Circuit Design
CN0267 combines three of ADI’s 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.
Using less than 1-mA of operating current it delivers more
processing-per-mW of power than any other analog microcontroller
within its class.
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 AD5421 consumes less than 300-µA
of quiescent current providing a 50 percent power saving and a 55
percent footprint saving over competing offerings.
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.
