EL8178

Micropower Single Supply Rail-to-Rail Input-Output (RRIO) Precision Op Amp

DATASHEET

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.

Features

• Typical 55µA supply current

• 250µV max offset voltage

• Typical 1pA input bias current

• 266kHz gain-bandwidth product

• Single supply operation between 2.4V to 5.5V

• Rail-to-rail input and output

• Ground sensing

• Output sources and sinks 26mA load current

• Pb-free (RoHS compliant)

Applications

• Battery- or solar-powered systems

• 4mA to 20mA current loops

• Handheld consumer products

• Medical devices

• Thermocouple amplifiers

• Photodiode pre-amps

• pH probe amplifiers
