ISL28138, ISL28238 4.5MHz, Single and Dual Precision Rail-to-Rail Input-Output (RRIO) Op Amps with Very Low Input Bias Current The ISL28138 and ISL28238 are 4.5MHz low-power single and dual 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 parts 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. The output operation is rail-to-rail. The parts draw minimal supply current (900µA per amplifier) while meeting excellent DC accuracy, AC performance, noise and output drive specifications. The ISL28138 features an enable pin that can be used to turn the device off and reduce the supply current to less than 20µA. Operation is guaranteed over -40°C to +125°C temperature range. Features • 4.5MHz gain bandwidth product • 900µA supply current (per amplifier) • 300µV maximum offset voltage • 1pA typical input bias current • Down to 2.4V single supply voltage range • Rail-to-rail input and output • Output sources and sinks 60mA load current • Enable pin (ISL28138) • -40°C to +125°C operation • Pb-free (RoHS compliant) Applications • Low-end audio • 4mA to 20mA current loops • Medical devices • Sensor amplifiers • ADC buffers • DAC output amplifiers Ordering Information PART NUMBER (Note) PART MARKING PACKAGE (Pb-free) PKG.
