General Description

The MAX4165–MAX4169 family of operational amplifiers

combines excellent DC accuracy with high output current

drive, single-supply operation, and rail-to-rail inputs and

outputs. These devices operate from a single +2.7V to

+6.5V supply, or from dual ±1.35V to ±3.25V supplies.

They typically draw 1.2mA supply current, and are guar-

anteed to deliver 80mA output current.

The MAX4166/MAX4168 have a shutdown mode that

reduces supply current to 38µA per amplifier and

places the outputs into a high-impedance state. The

MAX4165–MAX4169’s precision performance com-

bined with high output current, wide input/output

dynamic range, single-supply operation, and low power

consumption makes them ideal for portable audio

applications and other low-voltage, battery-powered

systems. The MAX4165 is available in the space-saving

5-pin SOT23 package and the MAX4166 is available in

a tiny 2mm x 2mm x 0.8mm µDFN package.
