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™).
