AD8532 250 mA Output, Dual Low Cost, Single-Supply Op Amp

The AD8531, AD8532 and AD8534 are single, dual and quad rail-to-rail input and 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 volt single supply as well as a 5 volt supply. Multimedia audio LCD drivers ASIC input or output amplifiers Headphone drivers

The very low input bias currents enable the AD853x to be used for integrators and diode amplification and other applications requiring low input bias current. Supply current is only 750 µA per amplifier at 5 volts, allowing low current applications to control high current loads.

Applications include audio amplification for computers, sound ports, sound cards and set-top boxes. AD853x family is very stable and 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 and AD8534 are specified over the extended industrial (–40°C to +85°C) temperature range. 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.
