General Description

The MAX4165–MAX4169 family of operational ampli-

fiers combines excellent DC accuracy with high output

current drive, single-supply operation, and Rail-to-Rail

inputs and outputs. These devices operate from a sin-

gle +2.7V to +6.5V supply, or from dual ±1.35V to

±3.25V supplies. They typically draw 1.2mA supply

current, and are guaranteed 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.

High-Output-Drive, Precision, Low-Power, SingleSupply, Rail-to-Rail I/O Op Amps with Shutdown MAX4165–MAX4169 Applications Information 6.5V Package Power Dissipation Warning: Due to the high output current drive, this op amp can exceed the absolute maximum power-dissipation rating. As a general rule, as long as the peak current is less than or equal to 80mA, the maximum package power dissipation will not be exceeded for any of the package types offered. There are some exceptions to this rule, however.
