GENERAL DESCRIPTION
The ADA4505-2/ADA4505-4 are 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 ADA4505-2/ADA4505-4
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/ADA4505-4 amplifiers.
The ADA4505-2/ADA4505-4 are specified for both the industrial
temperature range (−40°C to +85°C) and the extended industrial
temperature range (−40°C to +125°C). The ADA4505-2 dual
amplifier is available in standard 8-lead MSOP and 8-ball WLCSP
packages. The ADA4505-4 quad amplifier is available in 14-lead
TSSOP and 14-ball WLCSP packages.
The ADA4505-2/ADA4505-4 are members 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.

... This means that for a PSRR minimum in a typical op amp, the input-referred offset error is approximately 440 μV. If the same application uses the ADA4505-2/ADA4505-4 with a 100 dB minimum PSRR, the error is only 14 μ possible to calibrate this error out or to use an external voltage regulator to power the op amp, but these solutions can increase system cost and complexity ...

... CMRR minimum, an input-referred error of 790 μV is introduced. Another part with a CMRR minimum generates a 6.3 mV error. The ADA4505-2/ADA4505-4 CMRR minimum causes only a 79 μV error. As with the PSRR error, there are complex ways to minimize this error, but the ADA4505-2/ADA4505-4 solve this problem without incurring unnecessary circuitry complexity or increased cost ...
