AD8594ARZ GENERAL DESCRIPTION

The AD8591, AD8592, and AD8594 are single, dual, and quadrail-to-rail, input and output single-supply amplifiers featuring250 mA output drive current and a power saving shutdown mode.The AD8592 includes an independent shutdown function foreach amplifier. When both amplifiers are in shutdown mode,the total supply current is reduced to less than 1 μA. The AD8591and AD8594 include a single master shutdown function thatreduces the total supply current to less than 1 μA. All amplifieroutputs are in a high impedance state when in shutdown mode.These amplifiers have very low input bias currents, making themsuitable for integrators and diode amplification. Outputs are stablewith virtually any capacitive load. Supply current is less than750 μA per amplifier in active mode.Applications for these amplifiers include audio amplification forportable computers, portable phone headsets, sound ports, soundcards, and set-top boxes. The AD859x family is capable of drivingheavy capacitive loads, such as LCD panel reference levels.The ability to swing rail to rail at both the input and output enablesdesigners to buffer CMOS DACs, ASICs, and other wide outputswing devices in single-supply systems.
