FN7504.2
Micropower Single Supply Rail-to-Rail
Input-Output Precision Op Amp
The EL8178 is a micropower precision operational amplifier
optimized for single supply operation at 5V and can operate
down to 2.4V.
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.
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.

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.
