GENERAL DESCRIPTIONThe AD8541/AD8542/AD8544 are single, dual and quad rail-
to-rail input and output single supply amplifiers featuring very
low supply current and 1 MHz bandwidth. All are guaranteed to
operate from a +2.7 V single supply as well as a +5 V supply.
These parts provide 1 MHz bandwidth at low current consump-
tion of 45 µA per amplifier.
Very low input bias currents enable the AD8541/AD8542/AD8544
to be used for integrators, photodiode amplifiers, piezo electric
sensors and other applications with high source impedance. Supply
current is only 45 µA per amplifier, ideal for battery operation.
Rail-to-rail inputs and outputs are useful to designers buffering
ASICs in single supply systems. The AD8541/AD8542/AD8544
are optimized to maintain high gains at lower supply voltages,
making them useful for active filters and gain stages.
The AD8541/AD8542/AD8544 are specified over the extended
industrial (–40°C to +125°C) temperature range. The AD8541
is available in 8-lead SO and 5-lead SOT-23 packages. The
AD8542 is available in 8-lead SO, 8-lead MSOP, and 8-lead
TSSOP surface mount packages. The AD8544 is available in
14-lead narrow SO-14 and 14-lead TSSOP surface mount pack-
ages. All TSSOP, MSOP, and SOT versions are available in tape
and reel only.

NOTESStresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.For supplies less than +6 V, the differential input voltage is equal to ±VS.
ORDERING GUIDE*Available in reels only.
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD8541/AD8542/AD8544 features proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
PACKAGE INFORMATIONNOTEθJA is specified for worst case conditions, i.e., θJA is specified for device soldered
onto a circuit board for surface mount packages.
