A/D converters consume lowest power

BANGALORE, INDIA: Analog Devices Inc. (ADI) has introduced three ultra-low-power, multichannel, 12-bit, 1-MSPS SAR (successive approximation register) A/D converters.

The new 2, 4 and 8-channel A/D converters are designed for battery-powered data acquisition modules, handheld meters, field instruments and communications applications as well as medical devices such as portable electrocardiograms and heart rate monitors.

The A/D converters are the most power-efficient in their class, dissipating a maximum of 1.7 mW at 1 MSPS (mega-samples per second), which is over 60 percent less power than the closest SAR A/D converter competitor. The A/D converters are housed in a tiny 4-mm × 4-mm LFCSP package and feature a 5 ppm/°C typ on-chip internal reference.
