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.
