Analog Devices / Maxim Integrated MAX44290 Low-Offset Low-Power Op Amp

Analog Devices MAX44290 Low-Offset Low-Power Operational Amplifier offers a unique combination of high speed, precision, low noise, and low-voltage operation. This makes this device ideally suited for a large number of signal processing functions such as filtering and amplification of signals in portable and medical applications. 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. This operational amplifier's 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 Analog Devices MAX44290 Low-Offset Low-Power Op Amp is available in a tiny, 6-bump wafer-level package (WLP) with a 0.4mm pitch. The device 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.
