GENERAL DESCRIPTION

The AD8531, AD8532, and AD8534 are single, dual, and quad

rail-to-rail input/output single-supply amplifiers featuring

250 mA output drive current. This high output current makes

these amplifiers excellent for driving either resistive or capacitive

loads. AC performance is very good with 3 MHz bandwidth,

5 V/μs slew rate, and low distortion. All are guaranteed to operate

from a 3 V single supply as well as a 5 V supply.

The very low input bias currents enable the AD853x to be used for

integrators, diode amplification, and other applications requiring

low input bias current. Supply current is only 750 μA per

amplifier at 5 V, allowing low current applications to control

high current loads.

Applications include audio amplification for computers, sound

ports, sound cards, and set-top boxes. The AD853x family is

very stable, and it is capable of driving heavy capacitive loads

such as those found in LCDs.

The ability to swing rail-to-rail at the inputs and outputs enables

designers to buffer CMOS DACs, ASICs, or other wide output

swing devices in single-supply systems.

The AD8531/AD8532/AD8534 are specified over the extended

industrial temperature range (−40°C to +85°C). The AD8531 is

available in 8-lead SOIC, 5-lead SC70, and 5-lead SOT-23 packages.

The AD8532 is available in 8-lead SOIC, 8-lead MSOP, and 8-lead

TSSOP surface-mount packages. The AD8534 is available in

narrow 14-lead SOIC and 14-lead TSSOP surface-mount

packages.
