ISL28168, ISL28268  
Data Sheet  
July 25, 2011  
FN6378.4  
34µA Micro-power Single and Dual  
Rail-to-Rail Input-Output (RRIO) Low Input  
Bias Current Op Amps  
Features  
• 34µA typical supply current  
• 10pA typical input bias current  
• 200kHz gain bandwidth product  
• 2.4V to 5.5V single supply voltage range  
• Rail-to-rail input and output  
• Enable pin (ISL28168 only)  
• Pb-free (RoHS compliant)  
The ISL28168 and ISL28268 are micro-power operational  
amplifiers optimized for single supply operation over a power  
supply range of 2.4VDC to 5.5VDC. These devices draw  
minimal supply current and operate rail-to-rail at the input  
and output, while providing excellent DC-accuracy, noise  
and output drive specifications. Competing devices seriously  
degrade these parameters to achieve micro-power supply  
current.  
Applications  
The parts 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 0.25V above the positive  
supply and to 100mV below the negative supply with only a  
slight degradation of the CMRR performance. The output  
operation is rail-to-rail.  
• Battery- or solar-powered systems  
• 4mA to 20mA current loops  
• Handheld consumer products  
• Medical devices  
• Sensor amplifiers  
The 1/f corner of the voltage noise spectrum is at 100Hz.  
This results in low frequency noise performance, which can  
only be found on devices with an order of magnitude higher  
supply current.  
• ADC buffers  
• DAC output amplifiers  
Pinouts  
ISL28168 and ISL28268 can be operated from one lithium  
cell or two Ni-Cd batteries. The ISL28168 contains an enable  
pin feature that allows the device to be shutdown when not in  
use.
