AD8531

The AD8531, AD8532, and AD8534 are single, dual and quadrail-to-rail input and output single-supply amplifiers featuring250 mA output drive current. This high output current makesthese amplifiers excellent for driving either resistive or capacitiveloads. AC performance is very good with 3 MHz bandwidth,5 V/us slew rate and low distortion. All are guaranteed to oper-ate from a 3 volt single supply as well as a 5 volt supply.

The very low input bias currents enable the AD853x to be usedfor integrators, diode amplification and other applications requiringlow input bias current. Supply current is only 750 uA per amplifierat 5 volts, allowing low current applications to control highcurrent loads.

Applications include audio amplification for computers, soundports, sound cards and set-top boxes. The AD853x family isvery stable and capable of driving heavy capacitive loads, such asthose found in LCDs.

The ability to swing rail-to-rail at the inputs and outputs enablesdesigners to buffer CMOS DACs, ASICs or other wide outputswing devices in single-supply systems.

The AD8531, AD8532, and AD8534 are specified over theextended industrial (40 to +85) temperature range. TheAD8531. The AD8532 is available in 8-lead SOIC, MSOP,TSSOP surface-mount packages. The AD8534 is available in
narrow SO-14 and 14-lead TSSOP surface-mount packages.All TSSOP, SOT, and SC70 versions are available in tape and reel only.
