AD8624ARUZ-RL

低功耗，精密轨到轨输出运算放大器 Low Power, Precision Rail-to-Rail Output Op Amp

Product Details

The AD8624 is a quad, precision rail-to-rail output operational amplifier with a low supply current of only 350 μA maximum over temperature and supply voltages. It offers low offset, drift, and voltage noise combined with very low input bias currents over the full operating temperature range. With typical offset voltage of only 10 μV, offset drift of 0.5 μV/°C, and noise of only 0.2 μV p-p 0.1 Hz to 10 Hz, they are perfectly suited for applications where large error sources cannot be tolerated. Many systems can take advantage of the low noise, dc precision, and rail-to-rail output swing provided by the AD8622/AD8624 to maximize the signal-to-noise ratio and dynamic range for low power operation. The AD8622/ AD8624 are specified for the extended industrial temperature range of −40°C to +125°C. The AD8622 is available in lead-free 8-lead SOIC and MSOP packages, while the AD8624 is available in lead-free 14-lead TSSOP and 16-lead LFCSP packages.
