  Description

The ISL28288 and ISL28488 are dual and quad channel micropower operational amplifiers optimized for single supply operation over the 2.4V to 5.5V range. They can be operated from one lithium cell or two Ni-Cd batteries. For equivalent performance in a single channel op amp, reference EL8188.

These devices feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages 10% above the positive supply rail and to 100mV below the negative supply. The output operation is rail-to-rail.

The ISL28288 and ISL28488 draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. The ISL28288 (10 Ld MSOP only) contains a power-down enable pin that reduces the power supply current to typically less than 4μA in the disabled state.

 
  Key Features
 
  • Low power 120μA typical supply current
  • 1.5mV max offset voltage
  • 30pA max input bias current
  • 300kHz typical gain-bandwidth product
  • 105dB typical PSRR
  • 100dB typical CMRR
  • Single supply operation down to 2.4V
  • Input is capable of swinging above V+ and below V- (ground sensing)
  • Rail-to-rail input and output (RRIO)
  • Enable Pin - ISL28288 10 Ld MSOP package option only
  • Pb-free (RoHS compliant)
