DATASHEET ISL28156 FN6154 Rev 6.00 39A Micropower Precision Rail-to-Rail Input-Output (RRIO) Low Input Bias January 16, 2014 Current Op Amp The ISL28156 is a micropower precision operational Features amplifier optimized for single supply operation at 5V and can 39A typical supply current be operated down to 2.4V. 5nA max input bias current This device features an Input Range Enhancement Circuit (IREC), which enables it to maintain CMRR performance for 250kHz gain bandwidth product (A = 1) V input voltages greater than the positive supply. The input 2.4V to 5.5V single supply voltage range signal is capable of swinging 0.5V above a 5.0V supply Rail-to-rail input and output (0.25V for a 2.5V supply) and to within 10mV from ground. The output operation is rail-to-rail. Enable pin The 1/f corner of the voltage noise spectrum is at 1kHz. This Pb-free (RoHS compliant) results in low frequency noise performance, which can only be found on devices with an order of magnitude higher than Applications the supply current. Battery- or solar-powered systems The ISL28156 can be operated from one lithium cell or two 4mA to 20mA current loops Ni-Cd batteries. The input range includes both positive and Handheld consumer products negative rail. The output swings to both rails.
