GENERAL DESCRIPTION

–IN B

–IN A

The AD8505/AD8506/AD8508 are single, dual, and quad micro-

power amplifiers featuring rail-to-rail input/output swings while

operating from a single 1.8 V to 5 V power supply or from dual

±0.ꢀ V to ±±.5 V power supplies. Using a new circuit technology,

these amplifiers offer zero input crossover distortion (excellent

PSRR and CMRR performance) and 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.

This combination of features makes the AD8505/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. Remote battery-powered sensors, handheld

instrumentation, consumer equipment, hazard detection (for

example, smoke, fire, and gas), and patient monitors can benefit

from the features of the AD8505/AD8506/AD8508 amplifiers.

The AD8505/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 AD8505 single ampli-

fier is available in a tiny 5-lead SOT-±3 and a 6-ball WLCSP

packages. The AD8506 dual amplifier is available in 8-lead MSOP

and 8-ball WLCSP packages. The AD8508 quad amplifier is

available in 14-lead TSSOP and 14-ball WLCSP packages. The

AD8505/AD8506/AD8508 are members of a growing series of

zero crossover distortion op amps offered by Analog Devices,

Inc., including the ADA4505-1/ADA4505-±/ADA4505-4, that

operate from a single 1.8 V to 5 V supply or from dual ±0.ꢀ V to

±±.5 V power supplies.
