ADA4505-4ARUZ

ADA4505-4 is a quad channel, micropower amplifier. It features rail-to-rail input and output swings while operating from a single 1.8V to 5V power supply or from dual ±0.9V to ±2.5V power supplies. Employing a new circuit technology, this low cost amplifier offer zero input crossover distortion (excellent PSRR and CMRR performance) and very low bias current, while operating with a supply current of less than 10μA per amplifier. This combination of features make the 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 opamp. It is widely used in application such as pressure and position sensors, remote security, medical monitors, battery-powered consumer equipment, hazard detectors etc.
