Norwood, MA (12/01/2009) - Analog Devices, Inc. (ADI), the global leader in data-conversion technology for signal processing applications, today expanded its portfolio of precision sigma-delta ADCs (analog-to-digital converters) with 12- and 16-bit small-package devices that achieve new levels of noise performance and low-power operation for portable industrial and medical instrumentation equipment. The 12-bit AD7170 ADC and 16-bit AD7171 ADC have a 125-Hz output data rate and generate less noise than competing converters while consuming 25 percent less current. The new converters are designed for portable instrumentation, industrial process controls, medical monitoring devices, and other applications that require reliable, highly accurate signal conversion on a tight power budget within a confined PCB (printed circuit board) area.
The AD7170 and AD7171 achieve 12- and 16-bit noise-free resolution, respectively, meeting the demanding performance specifications of equipment used to precisely monitor patient vital signs and measure real-world instrumentation phenomena, such as pressure and temperature.
Key Features of the AD7170 and AD7171 Sigma-Delta ADCs
Recommended Complementary Components
Complementary components for the AD7171 ADC include the ADR5041 precision reference and the AD8628 precision amplifier. For the AD7170 ADC, the ADR5041 precision reference and the AD8631 precision amplifier are recommended.
