Description
The MAX44280 offers a unique combination of high speed, precision, low noise, and low-voltage operation making it ideally suited for a large number of signal processing functions such as filtering and amplification of signals in portable and industrial equipment. The amplifier features an input offset of less than 50FV and a high-gain bandwidth product of 50MHz while maintaining a low 1.8V supply rail. The device is internally compensated for gains of 5V/V or greater. The device’s rail-to-rail input/outputs and low noise guarantee maximum dynamic range in demanding applications such as 12- to 16-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 device includes a fast-power-on shutdown mode for further power savings. The IC operates from a supply range of 1.8V to 5.5V over the -40NC to +125NC temperature range and can operate down to 1.7V over the 0NC to +70NC temperature range. The MAX44280 is available in a small,6-pin SC70 package and is also available in a 1mm x 1.5mm thin µDFN (ultra-thin LGA) package.
