GENERAL DESCRIPTION AD8591ARTZ

The AD8591, AD8592, and AD8594 are single, dual, and quad rail-to-rail, input and output single-supply amplifiers featuring 250 mA output drive current and a power saving shutdown mode. The AD8592 includes an independent shutdown function for each amplifier. When both amplifiers are in shutdown mode, the total supply current is reduced to less than 1 μA. The AD8591 and AD8594 include a single master shutdown function that reduces the total supply current to less than 1 μA. All amplifier outputs are in a high impedance state when in shutdown mode.
