The AD8232 chip uses a two-pole high-pass filter to remove motion artifacts and electrode half-cell potentials. The filter is tightly coupled to the instrumentation amplifier structure to achieve single-stage high-gain and high-pass filtering, which saves space and cost; and uses an unconstrained op amp to create a three-pole low-pass filter that eliminates additional noise .
