ADA4505-2ARMZ-RL

ADA4505-2 dual micropower amplifier featuring rail-to-rail input and output. Employing a new circuit technology, these low cost amplifiers 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 makes the ADA4505-2 amplifiers 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 op-amp. Remote battery-powered sensors, handheld instrumentation and consumer equipment, hazard detectors (for example, smoke, fire and gas) and patient monitors can benefit from the features of the ADA4505-2 amplifiers.
