Complete HART modem IC unveiled by ADI

Analog Devices has introduced a complete HART (Highway Addressable Remote Transducer) modem IC (integrated circuit) AD5700 that enables HART connectivity in process control applications such as smart sensors and factory automation equipment.

"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."

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.
