说明

The MAX4122–MAX4129 family of operational amplifiers combines wide bandwidth and excellent DC accuracy with rail-to-rail operation at the inputs and outputs. These devices require only 650µA 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. The MAX4122/MAX4123/MAX4126/MAX4127/MAX4129 have a 5MHz gain bandwidth product, while the decompensated MAX4124/MAX4125/MAX4128 (stable at closed-looped gains of 10 or greater) have a 25MHz gain bandwidth product. In addition, the MAX4123/MAX4125/MAX4127 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, these amplifiers 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 MAX4122 and MAX4124 come in the space-saving 5-pin SOT23-5 package.
