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