FN6390.0

Dual Micropower, Single Supply, Rail-to-

Rail Input and Output (RRIO)

Instrumentation Amplifier

Features

• 120µA typical supply current for both channels

• 30pA max input bias current

The ISL28271 and ISL28272 are dual micropower

instrumentation amplifiers (in-amps) optimized for low 2.4V

to 5V single supplies.

• 100dB CMRR, PSRR

• 0.7µV/°C offset voltage temperature coefficient

• 180kHz 3dB Bandwidth - ISL28271

• 100kHz 3dB Bandwidth - ISL28272

• 0.5V/µs slew rate

Both devices feature an Input Range Enhancement Circuit

(IREC) which maintains CMRR performance for input

voltages equal to the positive and negative supply rails. The

input signal is capable of swinging 10% above the positive

supply rail and to 100mV below the negative supply with only

a slight degradation of the CMRR performance. The output

operation is rail to rail.

• Single supply operation

• Rail-to-rail input and output (RRIO)

• Input is capable of swinging above V+ and below V-

(ground sensing)

The ISL28271 is compensated for a minimum gain of 10 or

more. For higher gain applications, the ISL28272 is

compensated for a minimum gain of 100. The in-amps have

CMOS input devices for maximum input common voltage

range. The amplifiers can be operated from one lithium cell

or two Ni-Cd batteries.

• 0.081%1 typical gain error - ISL28271

• -0.19%1 typical gain error - ISL28272

• Pb-free plus anneal available (RoHS compliant)

Applications

Ordering Information

• Battery- or solar-powered systems

• Strain gauge

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100% matte

tin plate termination finish, which are RoHS compliant and compatible

with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that

meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
