AD8531

FEATURES Single-supply operation: 2.7 V to 6 V High output current: ±250 mA Low supply current: 750 μA/amplifier Wide bandwidth: 3 MHz Slew rate: 5 V/μs No phase reversal Low input currents Unity gain stable Rail-to-rail input and output APPLICATIONS Multimedia audio LCD drivers ASIC input or output amplifiers Headphone drivers 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 t...
