FN7504.5
Micropower Single Supply Rail-to-Rail
Input-Output (RRIO) Precision Op Amp
Features
• Typical 55μA supply current
• 250μV max offset voltage
The EL8178 is a precision low power, operational amplifier.
The device is optimized for single supply operation between
2.4V to 5V. This enables operation from one lithium cell or
two Ni-Cd batteries. The input range includes both positive
and negative rail.
• Typical 1pA input bias current
• 266kHz gain-bandwidth product
• Single supply operation between 2.4V to 5.0V
• Rail-to-rail input and output
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.
• Ground sensing
• Output sources and sinks 26mA load current
• Pb-free plus anneal available (RoHS compliant)

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.
