NORWOOD, Mass. — (BUSINESS WIRE) — April 27, 2009 — Analog Devices, Inc. ( ADI), a global leader in high-performance semiconductors for signal processing applications and leading provider of amplifier technology, introduced today the industry’s smallest and lowest power instrumentation amplifier ( in-amp). Smaller than the tip of a pencil, the miniscule size of the AD8235 in-amp, combined with its ultra-low power consumption, is effective for power-efficient and portable, lightweight medical devices and consumer-health products, including home-use ECG (electrocardiogram) monitors, infusion pumps and activity-monitoring medical devices. With 50% less power consumption than competitive offerings, the in-amp can enable designs to provide longer battery life. This performance is key for compact, wearable home-based medical devices that improve patient comfort while providing doctors with continuous and reliable patient monitoring.

The AD8235 measures 1.6 mm x 2.0 mm—one-third the size of competing instrumentation amplifiers. Operating on 1.8-V (min) and 5.5-V (max) power supplies and drawing only 40 microamps (max), the AD8235 is suitable for other low-power applications, including consumer-fitness products and industrial pressure and low-side current-sensing measurement equipment. These applications also benefit from the in-amp’s 6 nanoamp shutdown current and 40 picoamp bias current.

The AD8235’s wide power-supply range eliminates the need for extra supplies. The in-amp’s wide common-mode input-voltage range (4V and 1.4V on 5V and 1.8V supplies respectively) is important for the low-voltage operation required by many battery-powered portable applications. A high common-mode rejection ratio (CMRR) of 86 dB (gain=5) effectively eliminates common-mode interference.
