GENERAL DESCRIPTION
The 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.
