General Description
The MAX4165MAX4169 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 38A per amplifier and
places the outputs into a high-impedance state. The
MAX4165MAX4169'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.

ABSOLUTE MAXIMUM RATINGS
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.
