Micropower, Single Supply, Rail-to-Rail
Input-Output Instrumentation Amplifier
and Precision Operational Amplifier
The ISL28274 is a combination of a micropower
instrumentation amplifier (Amp A) with a low power precision
amplifier (Amp B) in a single package. The ISL28474 consist
of two micropower instrumentation amplifiers (Amp A) and
two low power precision amplifiers (Amp B) in a single
package. The amplifiers are optimized for operation at 2.4V
to 5V single supplies. Inputs and outputs can operate rail-to-
rail. As with all instrumentation amplifiers, a pair of inputs
provide a high common-mode rejection and are completely
independent from a pair of feedback terminals. The
feedback terminals allow zero input to be translated to any
output offset, including ground. A feedback divider controls
the overall gain of the amplifier. The additional precision
amplifier can be used to generate higher gain, with smaller
feedback resistors or used to generate a reference voltage.
The instrumentation amp (Amp A) is compensated for a gain
of 100 or more and the precision amp (Amp B) is unity gain
stable. Both amplifiers have PMOS inputs that provide less
than 30pA input bias currents.
The amplifiers can be operated from one lithium cell or two
Ni-Cd batteries. The amplifiers input range goes from below
ground to slightly above positive rail. The output stage
swings completely to ground or positive supply - no pull-up
or pull-down resistors are needed.

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.
