MAX4130–MAX4134
Single/Dual/Quad, Wide-Bandwidth, Low-Power,
Single-Supply, Rail-to-Rail I/O Op Amps
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-
mode voltage range that extends 250mV beyond VEE
and VCC. They are capable of driving 250Ω 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™).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
