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.
