  • The NCS325 is a CMOS operational amplifier providing precision performance. The Zero−Drift architecture allows for continuous auto−calibration, which provides very low offset, near−zero drift over time and temperature, and near flat 1/f noise at only 35 µA (max) quiescent current. These benefits make it ideal for precision DC applications. The NCS325 provides rail−to−rail input and output performance and is optimized for low voltage operation as low as 1.8 V and up to 5.5 V. The NCS325 is available in the space saving SOT23−5 package.
  • Features
