Description

The 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 amplifiers feature an input offset of less than 50FV
and a high-gain bandwidth product of 15MHz while maintaining a low 1.8V supply rail. 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.
