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.
