Micropower Single Supply Rail-to-Rail
Input-Output Precision Op Amp
The EL8188 is a micropower precision op amp optimized for
single supply operation at 5V and can operate down to 2.4V.
The EL8188 draws minimal supply current while meeting
excellent DC-accuracy, noise, and output drive
specifications. Competing devices seriously degrade these
parameters to achieve rail-to-rail operation and microamp
supply current. Offset current, voltage and current noise,
slew rate, and gain-bandwidth product are all 2X to 10X
better than on previous micropower rail-to-rail op amps.
The EL8188 can be operated from one lithium cell or two
Ni-Cd batteries. The input range includes both the positive
and negative rails. 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.
