Dual and Quad Channel Micropower,
Single Supply, Rail-to-Rail Input and
Output (RRIO) Instrumentation Amplifiers
The ISL28270 and ISL28273 are dual channel micropower
instrumentation amplifiers (in-amps) and the ISL28470 is a
quad channel in-amp optimized for single supply operation
over the +2.4V to +5.5V range.
All three devices feature an Input Range Enhancement
Circuit (IREC) which maintains CMRR performance for input
voltages equal to the positive supply and down to 50mV
above the negative supply rail. The input signal is capable of
swinging above the positive supply rail and to 10mV above
the negative supply with only a slight degradation of the
CMRR performance. The output operation is rail-to-rail.
The ISL28273 is compensated for a minimum gain of 10 or
more. For higher gain applications, the ISL28270 and
ISL28470 are compensated for a minimum gain of 100. The
in-amps have bipolar input devices for best offset and
excellent 1/f noise performance. 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.
