Dual Micropower, Single Supply, Rail-to-Rail Input and Output (RRIO) Instrumentation Amplifier
DATASHEET
Rev X.00
The ISL28271 and ISL28272 are dual micropower instrumentation amplifiers (in-amps) optimized for single supply operation over the +2.4V to +5.5V range.
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.
