FN6145.1  
Dual Micropower Single Supply  
Rail-to-Rail Input and Output (RRIO)  
Precision Op-Amp  
Features  
• Low Power 120µA typ supply current for both channels  
• 225µV max offset voltage  
The ISL28278 and ISL28478 are Dual and Quad channel  
micropower precision operational amplifier optimized for  
single supply operation at 5V and can operate down to 2.4V.  
For equivalent performance in a single channel op-amp  
reference EL8178.  
• 30pA typ input bias current  
• 300kHz gain-bandwidth product  
• 100dB typ PSRR and CMRR  
• Single supply operation down to 2.4V  
The ISL28278 and ISL28478 feature an Input Range  
Enhancement Circuit (IREC) which enables both parts to  
maintain CMRR performance for input voltages equal to the  
positive and negative supply rails. The input signal is  
capable of swinging 10% above the positive supply rail and  
to 100mV below the negative supply with only a slight  
degradation of the CMRR performance. The output  
operation is rail to rail.  
• Input is capable of swinging above V+ and below V-  
(ground sensing)  
• Rail-to-rail input and output (RRIO)  
• Pb-free plus anneal available (RoHS compliant)  
Applications  
• Battery- or solar-powered systems  
• 4mA to 25mA current loops  
• Handheld consumer products  
• Medical devices  
The both parts draw minimal supply current while meeting  
excellent DC-accuracy, AC-performance, noise and output  
drive specifications.  
The ISL28278 and ISL28478 can be operated from one  
lithium cell or two Ni-Cd batteries. The input range includes  
both positive and negative rail.  
• Thermocouple amplifiers  
• Photodiode pre-amps  
• pH probe amplifiers

NOTE: Intersil Pb-free plus anneal products employ special Pb-free  
material sets; molding compounds/die attach materials and 100%  
matte tin plate termination finish, which are 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.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
