Description

The MAX44290 offers a unique combination of high- speed, precision, 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.

This amplifier features an input offset of less than 50μV 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 device includes a fast-power-on shutdown mode for further power savings. The operational amplifier 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. It is available in a tiny 6-bump wafer level package (WLP), with 0.4mm-pitch.
