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
consists 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.
