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.
