NCS2325: Operational Amplifier, 75 µV Max Offset, 0.25 µV/C, 35 µA, Zero-Drift
The NCS2325 is a dual channel, 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 this device ideal for precision DC applications. These op amps provide rail−to−rail input and output performance and are optimized for low voltage operation as low as 1.8 V and up to 5.5 V.
