The AD8226 is a low-cost instrumentation amplifier with a wide supply range that just requires one external resistor to set any gain between 1 and 1000.
The AD8226 can deal with a wide range of signal voltages. The signal can make full use of the supply rails thanks to its wide input range and rail-to-rail output. Small signals near the ground can be amplified without the use of dual supplies because the input range includes the ability to descend below the negative supply. The AD8226 requires dual supplies ranging from 1.35 V to 18 V and single supplies ranging from 2.2 V to 36 V.
