Micropower Single Supply Rail-to-Rail
Input-Output (RRIO) Precision Op Amp
The EL8178 is a precision low power, operational amplifier.
The device is optimized for single supply operation between
2.4V to 5.5V. This enables operation from one lithium cell or
two Ni-Cd batteries. The input range includes both positive
and negative rail.
For power sensitive applications, the EL8178 has and EN
pin that will shut the device down and reduce the supply
current to 3µA typ. In the active state, the EL8178 draws
minimal supply current (55µA) while meeting excellent
DC-accuracy, noise, and output drive specifications.

NOTE:
1. 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.
