EL8188

Micropower Single Supply Rail-to-Rail

Input-Output Precision Op Amp

The EL8188 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.

The EL8188 draws minimal supply current (55µA) while

meeting excellent DC-accuracy, noise, and output drive

specifications.

Features

• Typical 55µA Supply Current

• 1mV 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

NOTES:

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

2. These Intersil Pb-free WLCSP and BGA packaged products

products employ special Pb-free material sets; molding

compounds/die attach materials and SnAgCu - e1 solder ball

terminals, which are RoHS compliant and compatible with both

SnPb and Pb-free soldering operations. Intersil Pb-free WLCSP

and BGA packaged products are MSL classified at Pb-free peak

reflow temperatures that meet or exceed the Pb-free requirements

of IPC/JEDEC J STD-020.
