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 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.
