GENERAL DESCRIPTION

The ADA4505-2 is a dual micropower amplifier featuring rail-

to-rail input and output swings while operating from a 1.8 V to

5 V single or from 0.ꢀ V to 2.5 V dual power supply.

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 amplifier.

Employing a new circuit technology, this low cost amplifier

offers 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.

The ADA4505-2 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 ADA4505-2 dual amplifiers are

available in the standard 8-lead MSOP package.

This combination of features makes the ADA4505-2 amplifier

an ideal choice for battery-powered applications because it

minimizes errors due to power supply voltage variations over

the lifetime of the battery, and maintains high CMRR even for a

rail-to-rail op amp.

The ADA4505-2 is a member of a growing series of zero crossover

op amps offered by Analog Devices, Inc., including the AD8506,

which also operates from a 1.8 V to 5 V single or from 0.ꢀ V to

2.5 V dual power supply.
