FN6337.4
4.5MHz, Single Dual and Quad Precision Rail-to-Rail Input-Output (RRIO) Op Amps with Very Low Input Bias Current
The ISL28148, ISL28248 and ISL28448 are 4.5MHz low-power single, dual and quad operational amplifiers. The parts are optimized for single supply operation from 2.4V to 5.5V, allowing operation from one lithium cell or two Ni-Cd batteries.
The single, dual and quad feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages greater than the positive supply. The input signal is capable of swinging 0.25V above the positive supply and to 100mV below the negative supply with only a slight degradation of the CMRR performance.
