Product Details

The MAX44259/MAX44260/MAX44261/MAX44263 offer a unique combination of high speed, precision, low noise, and low-voltage operation making them ideally suited for a large number of signal processing functions such as filtering and amplification of signals in portable and industrial equipment.

The devices’ rail-to-rail input/outputs and low noise guarantee maximum dynamic range in demanding applications such as 12- to 14-bit SAR ADC drivers. Unlike traditional rail-to-rail input structures, input crossover distortion is absent due to an optimized input stage with an ultra-quiet charge pump.

The MAX44260 includes a fast-power-on shutdown mode for further power savings. The MAX44261 offers a unique on-demand calibration pin where the user can invoke self-trimming of the input offset voltage. The MAX44263 is a dual amplifier.

The family of parts operates from a supply range of 1.8V to 5.5V over the -40°C to +125°C temperature range and can operate down to 1.7V over the 0°C to +70°C temperature range. The MAX44259 is offered in a 5-pin SOT23 package. The MAX44260/MAX44261 are available in small, 6-pin SC70 packages. The MAX44260 is also available in a 1mm x 1.5mm thin µDFN (ultra-thin LGA)package. The MAX44263 is available in a small 8-pin SC70 package.
