39µA Micropower Single and Dual  
Precision Rail-to-Rail Input-Output (RRIO)  
Low Input Bias Current Op Amps  
Features  
• 39µA typical supply current  
• 5nA max input bias current  
The ISL28156 and ISL28256 are micropower precision  
operational amplifiers optimized for single supply operation  
at 5V and can operated down to 2.4V.  
• 250kHz gain bandwidth product (A = 1)  
V
• 2.4V to 5.5V single supply voltage range  
• Rail-to-rail input and output  
These devices feature an Input Range Enhancement Circuit  
(IREC), which enables them to maintain CMRR performance  
for input voltages greater than the positive supply. The input  
signal is capable of swinging 0.5V above a 5.0V supply (0.25  
for a 2.5V supply) and to within 10mV from ground. The  
output operation is rail-to-rail.  
• Enable pin (ISL28156 only)  
• Pb-free (RoHS compliant)  
Applications  
• Battery- or solar-powered systems  
• 4mA to 20mA current loops  
• Handheld consumer products  
• Medical devices  
The 1/f corner of the voltage noise spectrum is at 1kHz. This  
results in low frequency noise performance, which can only  
be found on devices with an order of magnitude higher than  
the supply current.  
ISL28156 and ISL28256 can be operated from one lithium  
cell or two Ni-Cd batteries. The input range includes both  
positive and negative rail. The output swings to both rails.  
• Sensor amplifiers  
• ADC buffers  
• DAC output amplifiers

NOTE: These Intersil Pb-free plastic packaged products employ  
special Pb-free material sets; molding compounds/die attach  
materials and 100% matte tin plate PLUS ANNEAL - e3 termination  
finish, which is RoHS compliant and compatible with both SnPb and  
Pb-free soldering operations. Intersil Pb-free products are MSL  
classified at Pb-free peak reflow temperatures that meet or exceed  
the Pb-free requirements of IPC/JEDEC J STD-020.
