High-Output-Drive, Precision, Low-Power, Single-
Supply, Rail-to-Rail I/O Op Amps with Shutdown
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.

Continuous power dissipation should also be observed.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
