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-mode voltage range that extends 250mV
beyond V
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™).
