AD8546ARMZ

AD8546 is a dual micropower, high input impedance amplifier optimized for low power and wide operating supply voltage range applications. This 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 the sensor, front ends, or high-impedance input sources used in wireless or remote sensors or transmitters. This also has high immunity to electromagnetic interference. Applications includes portable medical equipment, remote sensors, transimpedance amplifiers, current monitors, 4mA to 20mA loop drivers, and buffer/level shifting.

• Maximum micropower at high voltage (18V) 22μA (IO=0mA, VSY=18V, VCM=VSY/2, TA=25°C)
