AD8508ACBZ-REEL GENERAL DESCRIPTION

The AD8505/AD8506/AD8508 are single, dual, and quad micro-power amplifiers featuring rail-to-rail input/output swings whileoperating from a single 1.8 V to 5 V power supply or from dual±0.9 V to ±2.5 V power supplies. Using a new circuit technology,these amplifiers offer zero input crossover distortion (excellentPSRR and CMRR performance) and low bias current whileoperating with a supply current of less than 20 μA per amplifier.This amplifier family offers the lowest noise in its power class.This combination of features makes the AD8505/AD8506/AD8508amplifiers ideal choices for battery-powered applications becausethey minimize errors due to power supply voltage variations overthe lifetime of the battery and maintain high CMRR even for a rail-to-rail input op amp. Remote battery-powered sensors, handheldinstrumentation, consumer equipment, hazard detection (forexample, smoke, fire, and gas), and patient monitors can benefitfrom the features of the AD8505/AD8506/AD8508 amplifiers.The AD8505/AD8506/AD8508 are specified for both the industrialtemperature range of −40°C to +85°C and the extended industrialtemperature range of −40°C to +125°C. The AD8505 single ampli-fier is available in a tiny 5-lead SOT-23 and a 6-ball WLCSPpackages. The AD8506 dual amplifier is available in 8-lead MSOPand 8-ball WLCSP packages. The AD8508 quad amplifier isavailable in 14-lead TSSOP and 14-ball WLCSP packages. TheAD8505/AD8506/AD8508 are members of a growing series ofzero crossover distortion op amps offered by Analog Devices,Inc., including the ADA4505-1/ADA4505-2/ADA4505-4, thatoperate from a single 1.8 V to 5 V supply or from dual ±0.9 V to±2.5 V power supplies.
