GENERAL DESCRIPTION

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.ꢀ5 V to ±± 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.
