Description

General part information

AD8546 Series

The AD8546 and AD8548 are dual and quad micropower, high input impedance amplifiers optimized for low power and wide operating supply voltage range applications.The AD8546 / AD8548 rail-to-rail input/output (RRIO) feature provides increased dynamic range to drive low frequency data converters, making these amplifiers ideal for dc gain and buffering of sensor front ends or high impedance input sources used in wireless or remote sensors or transmitters.The low supply current specification (22 µA) of the AD8546 / AD8548 over a wide operating voltage range of 2.7 V to 18 V or dual supplies (±1.35 V to ±9 V) makes these amplifiers useful for a variety of battery-powered, portable applications, such as ECGs, pulse monitors, glucose meters, smoke and fire detectors, vibration monitors, and backup battery sensors.The AD8546 / AD8548 are specified over the extended industrial temperature range of −40°C to +125°C. The AD8546 is available in an 8-lead MSOP package; the AD8548 is available in a 14-lead SOIC_N package.APPLICATIONSPortable medical equipmentRemote sensorsTransimpedance amplifiersCurrent monitors4 mA to 20 mA loop driversBuffer/level shifting
