Micropower, Single Supply, Rail-to-Rail

Input-Output Instrumentation Amplifier

and Precision Operational Amplifier

Features

• Combination of IN-AMP and OP-AMP in a single package

• 120µA supply current for ISL28274

• Input Offset Voltage IN-AMP 400µV max

• Input Offset Voltage OP-AMP 225µV max

• 30pA max input bias current

The ISL28274 is a combination of a micropower

instrumentation amplifier (Amp A) with a low power precision

amplifier (Amp B) in a single package. The ISL28474 consist

of two micropower instrumentation amplifiers (Amp A) and

two low power precision amplifiers (Amp B) in a single

package. The amplifiers are optimized for operation at 2.4V

to 5V single supplies. Inputs and outputs can operate rail-to-

rail. As with all instrumentation amplifiers, a pair of inputs

provide a high common-mode rejection and are completely

independent from a pair of feedback terminals. The

feedback terminals allow zero input to be translated to any

output offset, including ground. A feedback divider controls

the overall gain of the amplifier. The additional precision

amplifier can be used to generate higher gain, with smaller

feedback resistors or used to generate a reference voltage.

• 100dB CMRR and PSRR

• Single supply operation of 2.4V to 5.0V

• Ground Sensing

• Input voltage range is rail-to-rail and output swings

rail-to-rail

• Pb-free plus anneal available (RoHS compliant)

Applications

• 4-20mA loops

The instrumentation amp (Amp A) is compensated for a gain

of 100 or more and the precision amp (Amp B) is unity gain

stable. Both amplifiers have PMOS inputs that provide less

than 30pA input bias currents.

• Industrial Process Control

• Medical Instrumentations

The amplifiers can be operated from one lithium cell or two

Ni-Cd batteries. The amplifiers input range goes from below

ground to slightly above positive rail. The output stage

swings completely to ground or positive supply - no pull-up

or pull-down resistors are needed.

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
