39µA Micropower Single and Dual Rail-to-Rail Input-Output Low Input Bias Current (RRIO) Op Amps
The ISL28166 and ISL28266 are micropower precision operational amplifiers optimized for single supply operation at 5V and can operate down to 2.4V. These devices 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 0.5V above a 5.0V supply (0.25 for a 2.5V supply) and to within 10mV from ground. The output operation is rail-to-rail. The 1/f corner of the voltage noise spectrum at 1kHz. This results in low frequency noise performance, which can only be found on devices with an order of magnitude higher than the supply current. ISL28166 and ISL28266 can be operated from one lithium cell or two Ni-Cd batteries. The input range includes both positive and negative rail. The output swings to both rails.Features
