ISL28288, ISL28488
Dual and Quad Micropower Single Supply Rail-to-Rail Input and Output (RRIO)
Op Amp FN6339
Rev 4.00
July 26, 2011 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. Features 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. 250kHz typical gain-bandwidth product 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 4ВµA in the disabled
state. Input is capable of swinging above V+ and below V-(ground
sensing) Rail-to-rail input and output (RRIO) Related Literature Applications AN1344: ISL2828xEVAL1Z Evaluation Board User’s Guide Battery-or solar-powered systems Low power 60µA typical supply current per amplifier 1.5mV max offset voltage 30pA max input bias current 105dB typical PSRR 100dB typical CMRR Single supply operation down to 2.4V Enable Pin -ISL28288 10 Ld MSOP package option only Pb-free (RoHS compliant) 4mA to 25mA current loops Handheld consumer products Medical devices Thermocouple amplifiers Photodiode pre-amps pH probe amplifiers V+ VIN 0.082µF
