MAX4131

The MAX4131 family of operational amplifierscombines 10MHz gain-bandwidth product and excellentDC accuracy with rail-to-rail operation at the inputs andoutputs. 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 VEEand VCC. They are capable of driving 250Ωloads andare unity-gain stable. In addition, the MAX4131/MAX4133 feature a shutdown mode in which the outputsare placed in a high-impedance state and the supplycurrent is reduced to only 25µA per amplifier.

With their rail-to-rail input common-mode range andoutput swing, the MAX4131 is ideal for low-voltage, single-supply operation. Although the minimumoperating voltage is specified at 2.7V, the MAX4131 typically operate down to 1.8V. In addition, low offsetvoltage and high speed make them the ideal signal-conditioning stages for precision, low-voltage data-acquisition systems. The MAX4130 comes in thespace-saving SOT23-5 package.
