General Description

The MAX4130–MAX4134 family of operational amplifiers

combines 10MHz gain-bandwidth product and excellent

DC accuracy with rail-to-rail operation at the inputs and

outputs. These devices require only 900µA per amplifier,

and operate from either a single supply (+2.7V to +6.5V)

or dual supplies (±1.35V to ±3.25V) with a common-

Ω loads and

are unity-gain stable. In addition, the MAX4131/

MAX4133 feature a shutdown mode in which the outputs

are placed in a high-impedance state and the supply

current is reduced to only 25µA per amplifier.

With their rail-to-rail input common-mode range and

output swing, the MAX4130–MAX4134 are ideal for low-

voltage, single-supply operation. Although the minimum

operating voltage is specified at 2.7V, the devices

typically operate down to 1.8V. In addition, low offset

voltage and high speed make them the ideal signal-

conditioning stages for precision, low-voltage data-

acquisition systems. The MAX4130 is offered in the

space-saving 5-pin SOT23 package. The MAX4131 is

offered in the ultra-small 6-bump, 1mm x 1.5mm chip-

scale package (UCSP™).
