GENERAL DESCRIPTION
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 func-
tion for each amplifier. When both amplifiers are in shutdown
mode the total supply current is reduced to less than 1 A. The
AD8591 and AD8594 include a single master shutdown func-
tion that reduces total supply current to less than 1 A. All
amplifier outputs are in a high impedance state when in shut-
down mode.
These amplifiers have very low input bias currents, making them
suitable for integrators and diode amplification. Outputs are
stable with virtually any capacitive load. Supply current is less
than 750 A per amplifier in active mode.
Applications for these amplifiers include audio amplification for
portable computers, portable phone headsets, sound ports, sound
cards and set-top boxes. The AD859x family is capable of driving
heavy capacitive loads such as LCD panel reference levels.
The ability to swing rail-to-rail at both the input and output
enables 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, is
available in the 10-lead SOIC surface mount package. The
AD8594, quad, is available in 16-lead narrow SOIC and 16-lead
TSSOP packages.
