Typical Application Circuit for AD8505ACBZ-RL Four-Pole Butterworth Filter Used in a Glucose Meter. The AD8505 is a single Micro-power amplifier featuring rail-to-rail input/output swings while operating from a single 1.8V to 5V power supply or from dual |0.9V to |2.5V power supplies. Using a new circuit technology, these amplifiers offer zero input crossover distortion (excellent PSRR and CMRR performance) and low bias current while operating with a supply current of less than 20 uA per amplifier
