With Analog Devices ICs inside their designs, medical engineers are

dramatically improving the diagnostic experience for patients and

practitioners everywhere. Thats because ADI offers an industry-

leading portfolio of standard and application-tuned amplifiers, data

converters, microcontrollers, MEMS, low drop out regulators, anddigital isolators with unequaled performance, size, cost, and power

advantages. From imaging to monitoring to instrumentation, from

medical to consumer to communicationswherever user experience

defines the design, ADI is there.

To experience what Analog Devices ICs can do for your designs, visit

User experience defines the design;

ADI defines the possibilities

ICs that enable world-class diagnostics

for any patient, anywhere.

AD9271: 8-Channel Ultrasound ReceiverCombined LNA, VGA, AAF, ADC blocks reduce signal pathsize by 50%, power by 25%. Enables a new level of patientcare with accurate images in battery-powered equipmentfor nontraditional environments.

AD8339: Doppler Phase ShifterReplaces crosspoint switches and analog delay lines,saving up to 75% of board space, 30% of powerconsumption. Allows increased channel density and

CW Doppler capabilities in portable equipment.

AD7982: 1 MSPS, 18-Bit, 7 mW ADCCombines high accuracy, 95% less power, 80% lessspace than other ADCs. Enables patients to carry theircell-phone sized heart monitor all day long during theirhospital recovery.

ADuM240x: iCoupler 4-Channel Digital IsolatorReplaces optocouplers with an integrated solution toreduce costs and space up to 60%. Multiple channels of5 kV reinforced insulation in a single package simplifiesdesign, improves reliability. Approved for medical gradeisolation per IEC 60601-1.
