Характеристики

AD8531ARZ, Экономичный усилитель с однополярным питанием …The AD8531ARZ is a Single Rail-to-rail Input/Output Amplifier features single supply and 250mA output drive current. This high output current makes amplifier excellent for driving either resistive or capacitive loads. It is guaranteed to operate from a 3V single supply as well as a 5V supply. The very low input bias currents enable the AD8531 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 amplifier 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.
