MAXIM INTEGRATED PRODUCTS  MAX44261AXT+T  运算放大器, 轨至轨输入输出, 15 MHz, 1个放大器, 7 V/µs, 1.8V 至 5.5V, SC-70, 6 引脚

The is a low offset, low power, rail to rail I/O op-amp in 6 pin SC-70 package. This op-amp offers 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. The rail to rail input/output and low noise of MAX44261 provides maximum dynamic range in demanding applications such as 12bit to 14bit 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 MAX44261 offers a unique on-demand calibration pin where the user can invoke self trimming of input offset voltage. It is used in transimpedance amplifiers, analogue to digital converter, buffers and battery operated devices.
