MAX4323EUT+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P17
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 consume only
650µA per amplifier and operate from either a single sup-
ply (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 MAX4323 is offered in a small 6-bump chip-scale
package (UCSP™). The MAX4322/MAX4323 are also
available in space-saving SOT23 packages.
