Signal Chain Solution for 4-mA to 20-mA HART Enabled Field Instrument Applications
NORWOOD, Mass.–(BUSINESS WIRE)– Analog Devices, Inc. (NAS: 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.

• Find application notes and technical articles about field instrument solutions from ADI: http://processcontrol.analog.com/en/field-instruments-smart-transmitters/segment/pcia.html
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 …read more

Analog Devices’ Next Generation of Digital Power Controllers with PMBus Interface Targets Highest Density, Energy Efficient Isolated Power Converters
NORWOOD, Mass.–(BUSINESS WIRE)– Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, today introduced the ADP1051 advanced digital power controller with PMBus™ interface targeting ultra-compact, high density isolated DC-to-DC power supply systems with parallel/redundant capability. The ADP1051 is an extremely versatile digital controller with six PWM (pulse width modulation) logic outputs that can be programmed using an easy-to use graphic user interface (GUI) via the PMBus interface. The device enables high energy efficiency topologies including full bridge and active clamp forward variants with precision drive timing and control of secondary synchronous rectifiers. Energy efficiency is further optimised using adaptive dead-time compensation to improve the efficiency over the load range and programmable light load mode operation combined with low device power consumption (<100mW) to reduce system low power standby losses. The ADP1051 implements an extensive PMBus command set including the ability to accurately read input and output power measurements and enable the end-user to make intelligent system management decisions to optimize energy efficiency. The tiny size 4 x 4 mm LFCSP package makes the ADP1051 ideal for high density, ultra-compact isolated DC-to-DC power module or embedded designs for networking, communications and industrial applications ranging typically from 100 W upwards.

The ADP1051 power controller is easily programmed using an intuitive graphical-user interface which enables customers to design and store settings in the high reliability, internal EEPROM memory. The ADP1051 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability for increased current scaling. The device includes master/slave synchronization, reverse current protection and pre-bias start-up, accurate passive or droop current sharing between power supplies and a patented technique to identify and safely shutdown an erroneous power supply in parallel operation mode.
Key ADP1051 Features and Benefits:
- Small 4 x 4mm package enables ultra-compact isolated DC-to-DC design
