GENERAL DESCRIPTION

The AD8506/AD8508 are dual and quad micropower amplifiers

featuring rail-to-rail input and output swings while operating from

a 1.8 V to 5 V single or from ±0.9 V to ±±.5 V dual power supply.

Remote battery-powered sensors, handheld instrumentation

and consumer equipment, hazard detection (for example, smoke,

fire, and gas), and patient monitors can benefit from the features

of the AD8506/AD8508 amplifiers.

Using a novel circuit technology, these low cost amplifiers offer

zero crossover distortion (excellent PSRR and CMRR perform-

ance) and very low bias current, while operating with a supply

current of less than ±0 μA per amplifier. This amplifier family

offers the lowest noise in its power class.

The AD8506/AD8508 are specified for both the industrial

temperature range of −40°C to +85°C and the extended industrial

temperature range of −40°C to +1±5°C. The AD8506 dual amplifi-

ers are available in an 8-lead MSOP package. The AD8508 quad

amplifiers are available in the 14-lead TSSOP package.

This combination of features makes the AD8506/AD8508

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 input op amp.
