1. DESCRIPTION

The AD8531, AD8532, and AD8534ARUZ-REEL 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 AD8534ARUZ-REEL 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 AD8534ARUZ-REEL 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/AD8534ARUZ-REEL 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 AD8534ARUZ-REEL is available in narrow 14-lead SOIC and 14-lead TSSOP surface-mount packages.
