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.
