Single/Dual/Quad, Low-Cost, SOT23,
Low-Power, Rail-to-Rail I/O Op Amps
General Description
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.
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.
