The AD8505ARJZ-R7 is a single Micropower Amplifier with rail-to-rail input and output. Using a new circuit technology, this amplifier offers zero input crossover distortion (excellent PSRR and CMRR performance) and low bias current while operating with a supply current of less than 20μA per amplifier. This amplifier family offers the lowest noise in its power class. This combination of features makes the AD8505 amplifier ideal choices for battery-powered applications because they minimize errors due to power supply voltage variations over the lifetime of the battery and maintain high CMRR even for a rail-to-rail input op amp. Remote battery-powered sensors, handheld instrumentation, hazard detection (for example, smoke, fire and gas) and patient monitors can benefit from the features of the AD8505 amplifier.
