ISL28148, ISL28248
4.5MHz, Single and Dual Precision Rail-to-Rail Input-Output Op Amps with Very
Low Input Bias Current FN6337
Rev 5.00
January 22, 2016 The ISL28148, ISL28248 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. Features The single and dual 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. 1.8mV maximum offset voltage (ISL28248) The parts draw minimal supply current (900ВµA per amplifier)
while meeting excellent DC accuracy, AC performance, noise
and output drive specifications. The ISL28148 features an
enable pin that can be used to turn the device off and reduce
the supply current to a maximum of 16ВµA. Operation is
guaranteed across the -40В°C to +125В°C temperature range. 4.5MHz gain bandwidth product 900ВµA supply current (per amplifier) 1pA typical input bias current Down to 2.4V single supply operation Rail-to-rail input and output Enable pin (ISL28148 SOT-23 package only) -40В°C to +125В°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
