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 V

and V

. 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™).

MAX4130–MAX4134 Single/Dual/Quad, Wide-Bandwidth, Low-Power, Single-Supply, Rail-to-Rail I/O Op Amps Applications Information Rail-to-Rail Input Stage Devices in the MAX4130–MAX4134 family of highspeed amplifiers have rail-to-rail input and output stages designed for low-voltage, single-supply operation. The input stage consists of separate NPN and PNP differential stages that combine to provide an input common-mode range that extends 0.2V beyond the supply rails.

MAX4130–MAX4134 Single/Dual/Quad, Wide-Bandwidth, Low-Power, Single-Supply, Rail-to-Rail I/O Op Amps Rail-to-Rail Output Stage The minimum output voltage is within millivolts of ground for single-supply operation where the load is referenced to ground (VEE). Figure 3 shows the input voltage range and output voltage swing of a MAX4131 connected as a voltage follower. With a +3V supply and the load tied to ground, the output swings from 0.00V to 2.90V.
