AD8532AR

The AD8531, AD8532, and AD8534 are single, dual, and quad rail-to-rail input/output single-supply amplifiers featuring 250mA output drive current. This high-output current makes these amplifiers excellent for driving either resistive or capacitive loads. AC performance is very good with 3MHz bandwidth, 5V / μs slew rate, and low distortion. All are guaranteed to operate from a 3V single supply as well as a 5V 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 750μA per amplifier at 5V, 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).
