ADA4505-1/ADA4505-4

UMW

10 μA, Rail-to-Rail I/O, Zero Input

Crossover Distortion Amplifiers

GENERAL DESCRIPTION

FEATURES

PSRR: 100 dB minimum

CMRR: 105 dB typical

Very low supply current: 10 μA per amplifier maximum

1.8 V to 5 V single-supply or ±0.9 V to ±2.5 V dual-supply

operation Rail-to-rail input and output

3 mV offset voltage maximum

The

ADA4505-1/ADA4505-4

are

singleand

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.



Very low input bias current: 0.5 pA typical

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.

APPLICATIONS

Pressure and position sensors

Remote security

Medical monitors

Battery-powered consumer equipment

Hazard detectors



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).
