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 a low current consumption
of 45 mA 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. Sup-
ply current is only 45 mA 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 temperature range (–40∞C to +125∞C). The AD8541
is available in 8-lead SOIC, 5-lead SC70, and 5-lead SOT-23
packages. The AD8542 is available in 8-lead SOIC, 8-lead
MSOP, and 8-lead TSSOP surface-mount packages. The AD8544
is available in 14-lead narrow SOIC and 14-lead TSSOP surface-
mount packages. All MSOP, SC70, and SOT versions are available
in tape and reel only.

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.
