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.

AD8226 Theory of Operation
The AD8226 is based on the classic 3- op-amp topology. This topology has two stages: a preamplifier to provide differential amplification, followed by a difference amplifier to remove the common-mode voltage.
The benefits of the instrumentation amplifier include the following.
The gain of a three op-amp instrumentation amplifier circuit can be easily varied by adjusting the value of only one resistor regains.
The gain of the amplifier depends only on the external resistors used.
The input impedance is very high due to the emitter follower configurations of amplifiers 1 and 2
The output impedance of the instrumentation amplifier is very low due to the difference amplifier 3.
The CMRR of the op-amp 3 is very high and almost all of the common-mode signals will be rejected.
