General Description
____________________________Features
ꢀ SOT23 Packages (MAX4322/MAX4323)
ꢀ +2.4V to +6.5V Single-Supply Operation
ꢀ Rail-to-Rail Input Common-Mode Voltage Range
ꢀ Rail-to-Rail Output Voltage Swing
ꢀ 5MHz Gain-Bandwidth Product
The MAX4322/MAX4323/MAX4326/MAX4327/MAX4329
family of operational amplifiers combines wide bandwidth
and excellent DC accuracy with Rail-to-Rail® operation at
the inputs and outputs. These devices require only 650µA
per amplifier and operate from either a single supply
(+2.4V to +6.5V) or dual supplies ( 1.2V to 3.25V). These
unity-gain-stable amplifiers are capable of driving 250Ω
loads and have a 5MHz gain-bandwidth product. The
MAX4323 and MAX4327 feature a low-power shutdown
mode that reduces supply current to 25µA and places the
outputs in a high-impedance state.
ꢀ 650µA Quiescent Current per Amplifier
ꢀ 700µV Offset Voltage
ꢀ No Phase Reversal for Overdriven Inputs
ꢀ Drive 250Ω Loads
With their rail-to-rail input common-mode range and
output swing, these amplifiers are ideal for low-voltage,
single-supply operation. In addition, low offset voltage
and high speed make them the ideal signal-condition-
ing stages for precision, low-voltage data-acquisition
systems. The MAX4322/MAX4323 are available in
space-saving SOT23 packages.
