New product: A/D converter lowers power, space requirements

By Control Engineering Staff October 26, 2006
AD7980 analog-to-digital converter from Analog Devices consumes less power and less space.

Designed to increase the portability of patient and industrial monitors and improve the performance and throughput of data acquisition systems, Analog Devices’ AD7980 1-MSPS (mega-sample per second) 16-bit analog-to-digital converter (ADC) consumes 80% less power and board space than the closest competing 16-bit ADC in its class.

These power and size advantages allow designers to incorporate the new ADC and a digital interface into the new breed of highly integrated “smart sensors,” which eliminate the parasitic effects, signaling errors and delayed response time caused when the ADC is physically separated from the sensor using signal cables. In industrial sensing applications, this allows equipment operators to more easily and accurately measure changes in vibration, pressure and temperature that can degrade system operation. The unit’s fast sampling rate and low power consumption allow designers to place critical components closer together to improve system performance and speed.

The AD7980 1-MSPS 16-bit PulSar ADC is sampling now in 10-lead MSOP and LFCSP packages, with production quantities available in the second quarter of 2007. The unit is priced at $19.50 in 1,000-unit quantities. For more information, visit .
