High-Output-Drive, Precision, Low-Power, Single-
Supply, Rail-to-Rail I/O Op Amps with Shutdown
5–MAX4169
General Description
Features
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.ꢀ5V to ꢀ.25V supplies.
They typically draw 1.2mA supply current, and are guar-
anteed to deliver 80mA output current.
♦ 80mA (min) Output Drive Capability
♦ Rail-to-Rail Input Common-Mode Voltage Range
♦ Rail-to-Rail Output Voltage Swing
♦ 1.2mA Supply Current per Amplifier
♦ +2.7V to +6.5V Single-Supply Operation
♦ 5MHz Gain-Bandwidth Product
The MAX4166/MAX4168 have a shutdown mode that
reduces supply current to ꢀ8µA 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 SOT2ꢀ package and the MAX4166 is available in
a tiny 2mm x 2mm x 0.8mm µDFN package.
♦ 250µV Offset Voltage
♦ 120dB Voltage Gain (R = 100kΩ)
♦ 88dB Power-Supply Rejection Ratio
♦ No Phase Reversal for Overdriven Inputs
♦ Unity-Gain Stable for Capacitive Loads to 250pF
L
♦ Low-Power Shutdown Mode:
Reduces Supply Current to 38µA Places
Outputs in High-Impedance State
♦ Available in 5-Pin SOT23 Package (MAX4165) or
2mm x 2mm x 0.8mm µDFN (MAX4166)
