GENERAL DESCRIPTION
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 A) 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.
