The ADA4505-1/ADA4505-2/ADA4505-4 are single, dual, and quad micropower amplifiers featuring rail-to-rail input and output swings while operating from a single 1.8 V to 5 V power supply or from dual ±0.9 V to ±2.5 V power supplies.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 10 μA per amplifier.This combination of features makes the ADA4505-x 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-x amplifiers.The ADA4505-x family is specified for both the industrial temperature range (−40°C to +85°C) and the extended industrial temperature range (−40°C to +125°C). The ADA4505-1 single amplifier is available in a tiny 5-lead SOT-23. The ADA4505-2 dual amplifier is available in a standard 8-lead MSOP and a 8-ball WLCSP. The ADA4505-4 quad amplifier is available in a 14-lead TSSOP and a 14-ball WLCSP.The ADA4505-x family is a member of a growing series of zero crossover op amps offered by Analog Devices, Inc., including the AD8506/AD8508, which also operate from a single 1.8 V to 5 V power supply or from dual ±0.9 V to ±2.5 V power supplies.Applications Pressure and position sensors Remote security Medical monitors Battery-powered consumer equipment Hazard detectors
