_______________General Description
The MAX4130MAX4134 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 900A 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-
mode voltage range that extends 250mV beyond V
EE
and V
CC
. They are capable of driving 250
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 25A per amplifier.
With their rail-to-rail input common-mode range and
output swing, the MAX4130MAX4134 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 comes in the
space-saving SOT23-5 package.
