Analog Devices Inc. ADA4505-1, ADA4505-2, and ADA4505-4 Micropower Amplifiers are single, dual, and quad operational amplifiers featuring rail-to-rail input and output. The ADA4505-1, ADA4505-2, and ADA4505-4 amplifiers can operate from a single 1.8V to 5.0V power supply or from dual ±0.9V to ±2.5V power supplies. These devices 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 Amplifiers ideal choices for battery-powered applications. These devices minimize errors due to power supply voltage variations over the battery's lifetime and maintain high CMRR even for a rail-to-rail op-amp.
