The AD8546 is a dual, micropower, high input impedance amplifier optimized for low power and wide operating supply voltage range applications. The AD8546 RRIO provides increased dynamic range to drive low frequency data converters, which is ideal for dc gain and buffering of sensor front ends or high impedance input sources in wireless or remote sensors or transmitters. The AD8546 specification of low supply current (22 μA) over the wide range of operating voltage 2.7 V to 18 V or dual supplies (±1.35 V to ±9 V) makes it 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 is specified over the extended industrial temperature range of −40°C to +125°C and is available in an 8-lead MSOP.
