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.

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.ꢀ V to 2.5 V power supplies.

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 a 14-lead

TSSOP package.

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.

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.ꢀ V to 2.5 V

power supplies.
