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 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.  
14-Lead SOIC and TSSOP  
(R and RU Suffixes)  
The AD8541/AD8542/AD8544 are specified over the extended  
industrial temperature range (–40C to +125C). 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.
