GENERAL DESCRIPTION

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 and a 6-ball WLCSP.

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

AD8505/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.
