ISL28276
Dual Precision Micropower Single Supply
Rail-to-Rail Input and Output Precision
Op-Amps
The ISL28276 is a dual channel micropower precision
operational amplifier optimized for single supply operation at
5V and can operate down to 2.4V. For equivalent
performance in a single channel op-amp reference EL8176.
The ISL28276 features an Input Range Enhancement Circuit
(IREC) which enables the ISL28276 to maintain CMRR
performance for input voltages greater than the positive
supply. The input signal is capable of swinging 0.5V above a
5.0V supply (0.25V for a 2.4V supply) and to within 10mV
from ground. The output operation is rail to rail.
The ISL28276 draws minimal supply current while meeting
excellent DC-accuracy, AC-performance, noise and output
drive specifications. Offset current, voltage and current
noise, slew rate, and gain-bandwidth product are all two to
ten times better than other micropower op-amps with
equivalent supply current ratings.
The ISL28276 can be operated from one lithium cell or two
Ni-Cd batteries. The input range includes both positive and
negative rail.
Features
• 120µA supply current for both channels
• 100µV max offset voltage
• 500pA input bias current
• 400kHz gain-bandwidth product
• 115dB PSRR and CMRR
• Single supply operation down to 2.4V
• Input is capable of swinging above V+ and within 10mV of
Ground
• Rail-to-rail output
• Output sources 31mA load current
• Pb-free plus anneal available (RoHS compliant)
Applications
• Battery- or solar-powered systems
• 4mA to 25mA current loops
• Handheld consumer products
• Medical devices
• Thermocouple amplifiers
• Photodiode pre-amps
• pH probe amplifiers

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.
