MAX44280AXT+T

The MAX44280AXT+T is a 1.8V, 50MHz, rail to rail I/O op-amp in 6 pin SC-70 package. This op-amp 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 12bit to 16bit SAR ADC drivers. It includes a fast-power-on shutdown mode for further power savings. Device is used in 3G/4G handsets, ADC buffers and transimpedance amplifiers.
