PRELIMINARY
Micropower Single Supply Rail-to-Rail
Input-Output Precision Op Amp
Features
• 50µA supply current
The EL8178 is a micropower precision operational amplifier
optimized for single supply operation at 5V and can operate
down to 2.4V.
• 100µV max offset voltage
• 1pA input bias current
• 250kHz gain-bandwidth product
• 0.13V/µs slew rate
The EL8178 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.
• 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)
The EL8178 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.
Applications
• Battery- or solar-powered systems
• 4mA to 20mA current loops
• Handheld consumer products
• Medical devices

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.
