Data Sheet

FN6390.0  
Dual Micropower, Single Supply, Rail-to-  
Rail Input and Output (RRIO)  
Instrumentation Amplifier  
Features  
• 120µA typical supply current for both channels  
• 30pA max input bias current  
The ISL28271 and ISL28272 are dual micropower  
instrumentation amplifiers (in-amps) optimized for low 2.4V  
to 5V single supplies.  
• 100dB CMRR, PSRR  
• 0.7µV/°C offset voltage temperature coefficient  
• 180kHz 3dB Bandwidth - ISL28271  
• 100kHz 3dB Bandwidth - ISL28272  
• 0.5V/µs slew rate  
Both devices feature an Input Range Enhancement Circuit  
(IREC) which maintains 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.  
• Single supply operation  
• Rail-to-rail input and output (RRIO)  
• Input is capable of swinging above V+ and below V-  
(ground sensing)  
The ISL28271 is compensated for a minimum gain of 10 or  
more. For higher gain applications, the ISL28272 is  
compensated for a minimum gain of 100. The in-amps have  
CMOS input devices for maximum input common voltage  
range. The amplifiers can be operated from one lithium cell  
or two Ni-Cd batteries.  
• 0.081%1 typical gain error - ISL28271  
• -0.19%1 typical gain error - ISL28272  
• Pb-free plus anneal available (RoHS compliant)  
Applications  
Ordering Information  
• Battery- or solar-powered systems  
• Strain gauge

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.
