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 a low current consumption
of 45 μA per amplifier.
Very low input bias currents enable the AD8541/AD8542/AD8544
to be used for integrators, photodiode amplifiers, piezoelectric
sensors, and other applications with high source impedance.
The 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 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.
