Single, Dual and Quad Micropower Single
Supply Rail-to-Rail Input and Output
(RRIO) Precision Op Amp
The ISL28176, ISL28276 and ISL28476 are single, dual and
quad channel micropower operational amplifiers optimized
for single supply operation over the 2.4V to 5V range. They
can be operated from one lithium cell or two Ni-Cd batteries.
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 down to
the negative supply. The output operation is rail-to-rail.
The ISL28276 and ISL28476 draw minimal supply current
while meeting excellent DC-accuracy, AC-performance,
noise and output drive specifications. The ISL28276 (QSOP
package only) contains a power-down enable pin that
reduces the power supply current to typically 4µA in the
disabled state.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is 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.
Features
• Low power 120µA typical supply current (ISL28276)
• 100µV maximum offset voltage
• 500pA typical input bias current
• 400kHz typical gain-bandwidth product
• 115dB typical PSRR and CMRR
• Single supply operation down to 2.4V
• Input is capable of swinging above V+ and to V- (ground
sensing)
• Rail-to-rail input and output (RRIO)
• Pb-free (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
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
1. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
Electrical Specifications
V+ = 5V, V- = 0V,VCM = 2.5V, RL = Open, TA = +25°C unless otherwise specified.
Boldface limits apply over the operating temperature range, -40°C to +125°C, temperature data
established by characterization.
