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 shutdownmode. The AD8592 includes an independent shutdown function for each amplifier. When both amplifiers are in shutdownmode the total supply current is reduced to less than 1 m A. TheAD8591 and AD8594 include a single master shutdown function that reduces total supply current to less than 1 m A. Allamplifier outputs are in a high impedance state when in shut-down mode.

These amplifiers have very low input bias currents, making themsuitable for integrators and diode amplification. Outputs arestable with virtually any capacitive load. Supply current is lessthan 750 m A 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 outputenables designers to buffer CMOS DACs, ASICs and other wide output swing devices in single supply systems.

The AD8591, AD8592 and AD8594 are specified over the indus-trial (40 C to +85 C) temperature range. The AD8591, single,is available in the tiny 6-lead SOT package. The AD8592, dual, isavailable in the 10-lead m SOIC surface mount package. TheAD8594, quad, is available in 16-lead narrow SOIC and 16-leadTSSOP packages.
