DATASHEET

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

Features

micropower operational amplifiers optimized for single supply

• Low power 60µA typical supply current per amplifier

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.

• 1.5mV max offset voltage

• 30pA max input bias current

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

• 105dB typical PSRR

• 100dB typical CMRR

• Single supply operation down to 2.4V

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.

• 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)

• 4mA to 25mA current loops

• Handheld consumer products

• Medical devices

• Thermocouple amplifiers

• Photodiode pre-amps

• pH probe amplifiers
