Dual Micropower, Single Supply, Rail-to-
Rail Input and Output (RRIO)
Instrumentation Amplifier
The ISL28271 and ISL28272 are dual micropower
instrumentation amplifiers (in-amps) optimized for low 2.4V
to 5V single supplies.
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.
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.

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.
