WIRE)-- Analog Devices, Inc.,
(ADI) a global leader in high-performance semiconductors for signal
processing applications, today 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 has been tested by the HART Communication
Foundation to verify that products designed with the new ADI device
will adhere to HART protocol requirements,” said Ron Helson, executive
director, HART Communication Foundation. “Compliance with HART protocol
requirements is important so users worldwide can gain quick, easy visibility
to devices in the field when using HART-enabled handheld test, calibration
devices, computers and automation systems.”
The AD5700 HART
modem IC accurately encodes and decodes HART communication signals in
noisy, harsh industrial environments, ensuring a reliable communication
interface. The AD5700 HART modem IC makes it quick and easy to implement
products that can be registered with the HART Communication Foundation.
The new modem IC requires 60 percent less external support components
and is the first to incorporate an internal low-power 0.5 percent accurate
oscillator, 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.
HART modem IC is designed to interface easily with ADI’s innovative
portfolio of data converters for industrial applications, such as the
AD5755 D/A converter for analog I/O modules and the
AD5421 D/A converter for loop-powered smart transmitter applications.
ADI has also developed a fully functional smart transmitter demo system
featuring the AD5700 HART modem IC that is compliance tested, verified
and registered with the HART Communication Foundation as an approved
AD5700 HART Modem IC Key Features and
Integrates in a single chip all the necessary
filtering, signal detection, modulation, demodulation and signal generation
functions needed to achieve HART connectivity, so designs require few
external support components.
Integrated, low power, 0.5 percent
accurate oscillator is a compact alternative to a discrete crystal.
Meets the industry standard for physical layer protocols set by
the HART Communication Foundation and simplifies design challenges by
accounting for all physical layer requirements.
a wide industrial temperature range of –40°C to +125°C, enabling use
in high and low temperature environments.
