ANALOG DEVICES INTRODUCES INDUSTRY’S LOWEST POWER COMPLETE HART MODEM IC FOR PROCESS CONTROL APPLICATIONS

Analog Devices Introduces Industry’s Lowest Power Complete HART Modem IC for Process Control Applica

Norwood, MA (02/28/2012) - Analog Devices, Inc., 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.

The AD5700 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.

AD5700 HART Modem IC Key Features and Benefits

  • 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.
  • Specified for a wide industrial temperature range of –40°C to +125°C, enabling use in high and low temperature environments.
