Product Description

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 (±1.35 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.
FEATURES
Micropower at high voltage: 22 μA maximum
Low input bias current: 20 pA maximum
Gain bandwidth product: 240 kHz
Slew rate: 80 V/ms
Large signal voltage gain: 110 dB minimum
Single-supply operation: 2.7 V to 18 V
Dual-supply operation: ±1.35 V to ±9 V
Unity-gain stable
APPLICATIONS
Portable medical equipment
Remote sensors
Transimpedance amplifiers
Current monitors
4 mA to 20 mA loop drivers
Buffer/level shifting
