Product Overview NCS325: Single Operational Amplifier, 50 µV Offset, 0.25 µV/°C, Zero-Drift Precision, Low Power For complete documentation, see the data sheet Product Description 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.
