Description

The ISL28271 and ISL28272 are dual micropower instrumentation amplifiers (in-amps) optimized for low 2.4V to 5V single supplies.

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.

The ISL28271 is compensated for a minimum gain of 10 or more. For higher gain applications, the ISL28272 is compensated for a minimum gain of 100. The in-amps have CMOS input devices for maximum input common voltage range. The amplifiers can be operated from one lithium cell or two Ni-Cd batteries.
