AD8505ARJZ-R7

AD8505 is a single channel, micropower 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, 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 offers the lowest noise in its power class. This combination of features make the device ideal choices for battery-powered applications because it minimizes 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. It is used in applications such as pressure and position sensors, remote security, bio sensors, IR thermometers, battery-powered consumer equipment, hazard detectors.
