Analog Devices Introduces SST-Enabled Temperature and Voltage Sensors for Desktop Computers, Servers and Workstations

Posted on: Tuesday, 13 June 2006, 12:00 CDT

Designed for the Simple Serial Transport (SST) bus co-developed by Analog Devices and Intel, temperature and voltage sensors expand ADI's offering of power management devices while enabling customers to leverage next-generation features built into computing chipsets from Intel.

Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing applications, today introduced a family of digital temperature and voltage sensors for use in desktop computers and workstations that employ the Simple Serial Transport(TM) (SST(TM)) bus. Combining ADI's expertise in converter and power management technologies, the ADT748x family of sensors incorporates a 10-bit analog-to-digital converter (ADC) to provide accurate, high-performance communication of temperature and voltage levels over a reliable, high-speed environmental management bus. In addition to monitoring temperature and voltage, the new family also allows designers to use emerging features found in next-generation Intel core-logic chipsets to further enhance overall system performance and efficiency.

"Analog Devices continues to develop and bring to market more accurate and innovative power management and monitoring solutions that drive platform performance in desktop PCs, servers and workstations," said John Blake, product line director, Power and Thermal Management, Analog Devices. "By supporting the SST bus, the ADT748x family provides a sensor solution that relays information related to temperature and voltage directly to the core logic, and in real time. Leveraging the speed and accuracy of the SST bus, ADI's digital temperature and voltage sensors take full advantage of Intel's next-generation chipset features, such as its Quiet Platform Technology, which reduces the number of discrete fan control components in the system, thereby lowering BOM costs."

Power Monitoring with the ADT748x Family of Temperature and Voltage Sensors

The ADT748x family operates at speeds over 1 Mbps (megabits-per-second) and is housed in a small package (8-pin or 10-pin MSOP) for easy placement in areas where space is at a premium. The ADT7484A and ADT7486A are simple, 1-degree centigrade accurate, digital temperature sensors that monitor their own temperature, as well as one (ADT7484A) or two (ADT7486A) remote sensor diodes. The ADT7485A digital temperature sensor and voltage monitor can sense its own temperature, as well as that of a remote sensor diode. The ADT7485A can also monitor four external voltage channels and its own supply voltage using its on-board 10-bit ADC (analog-to-digital converter). A single, bidirectional SST data line controls all the devices in the ADT784x family.

The SST (Simple Serial Transport) Bus

The result of a collaborative design effort between Analog Devices and Intel Corporation, the SST bus relays key environmental information, such as temperature and voltage, to the core logic or dedicated ASIC fan-speed controllers, improving reliability and performance in PCs, servers and workstations. The SST bus is the fastest, most robust, noise-immune and scalable interface available for communicating environmental data. Thermal sensors using the SST bus incur only one error for every billion bits processed. Other high-performance options, such as the SMBus (System Management Bus), measure about one error every 10,000 bits when tested in the same environment on new PC motherboards.

Availability and Pricing

The ADT748x family of temperature sensors are sampling now with volume production scheduled for June 2006. The devices are priced at $1.50 per unit in 1,000-piece quantities. The ADT7484A is available in an 8-lead MSOP, and the ADT7485A and ADT7486A are available in 10-lead MSOP packaging.
