Maxim MAX4322EUA, MAX4322ESA, MAX4329ESD, MAX4327EUB, MAX4327ESD Datasheet

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-condition­ing stages for precision, low-voltage data-acquisition
systems. The MAX4322/MAX4323 are available in
space-saving SOT23 packages.

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.
