Micropower Single Supply Rail-to-Rail
Input-Output Op Amp
The EL8186 is a micropower operational amplifier optimized
for single supply operation at 5V and can operate down to
2.4V.
The EL8186 draws minimal supply current while meeting
excellent DC-accuracy noise and output drive specifications.
Competing devices seriously degrade these parameters to
achieve micropower supply current. Offset current, voltage
and current noise, slew rate, and gain-bandwidth product are
all two to ten times better than on previous micropower op
amps.
The EL8186 can be operated from one lithium cell or two
Ni-Cd batteries. The input range includes both positive and
negative rail. The output swings to both rails.
Features
• 55µA supply current
• 400µV typical offset voltage
• 500pA input bias current
• 400kHz gain-bandwidth product
• 1MHz -3dB bandwidth
• 0.13V/µs slew rate
• Single supply operation down to 2.4V
• Rail-to-rail input and output
• Output sources and sinks 26mA 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.
