• Typical Application Circuit for AD8546ARMZ 4 mA to 20 mA Current Loop Transmitter. The AD8546 is a dual Micro-power, high input impedance amplifier optimized for low power and wide operating supply voltage range applications. The AD8546 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
