FN6378.4

34µA Micro-power Single and Dual

Rail-to-Rail Input-Output (RRIO) Low Input

Bias Current Op Amps

Features

• 34µA typical supply current

• 10pA typical input bias current

• 200kHz gain bandwidth product

• 2.4V to 5.5V single supply voltage range

• Rail-to-rail input and output

• Enable pin (ISL28168 only)

• Pb-free (RoHS compliant)

The ISL28168 and ISL28268 are micro-power operational

amplifiers optimized for single supply operation over a power

supply range of 2.4VDC to 5.5VDC. These devices draw

minimal supply current and operate rail-to-rail at the input

and output, while providing excellent DC-accuracy, noise

and output drive specifications. Competing devices seriously

degrade these parameters to achieve micro-power supply

current.

Applications

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.

• Battery- or solar-powered systems

• 4mA to 20mA current loops

• Handheld consumer products

• Medical devices

• Sensor amplifiers

The 1/f corner of the voltage noise spectrum is at 100Hz.

This results in low frequency noise performance, which can

only be found on devices with an order of magnitude higher

supply current.

• ADC buffers

• DAC output amplifiers

Pinouts

ISL28168 and ISL28268 can be operated from one lithium

cell or two Ni-Cd batteries. The ISL28168 contains an enable

pin feature that allows the device to be shutdown when not in

use.
