AD7091R - The 12-bit 1-MSPS SAR A/D converter
Norwood, MA (09/05/2012) - Analog Devices, Inc. (ADI), Introduced the first product in a series of ultra-low-power, 12-bit, 1-MSPS SAR (successive approximation register) A/D converters with internal 2.5-V reference. The new A/D converter is designed for USB (universal serial bus) or battery powered data acquisition modules, handheld meters, field instruments, energy harvesting applications and medical devices such as portable electrocardiograms and heart rate monitors. The most power-efficient converter in its class, the device dissipates over 70 percent lower power than the closest SAR A/D converter competitor, in a package that is 33 percent smaller than competing 12-bit converters with internal reference.
