Features
5MHz gain bandwidth product @ AV = 100 13MHz -3db unity gain bandwidth 950µA typical supply current (per amplifier) 650µV maximum offset voltage (6 Ld SOT-23) 16nA typical input bias current Down to 2.4V single supply voltage range Rail-to-rail input and output Enable pin (ISL28146 only) -40°C to +125°C operation Pb-free (RoHS compliant)
operational amplifiers optimized for single supply operation from 2.4V to 5.5V, allowing operation from one lithium cell or two Ni-Cd batteries. They feature a gain-bandwidth product of 5MHz and are unity-gain stable with a -3dB bandwidth of 13MHz. 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 0.25V above a 5.0V supply and to within 10mV from ground. The output operation is rail-to-rail. The parts draw minimal supply current while meeting excellent DC accuracy, AC performance, noise and output drive specifications. The ISL28146 features an enable pin that can be used to turn the device off and reduce the supply current to only 16µA. Operation is guaranteed over -40°C to +125°C temperature range.
