The NCS325, NCS2325 and NCS4325 are CMOS operational amplifiers 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 these devices 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. The single channel NCS325 is available in the space−saving SOT23−5 package. The dual channel NCS2325 is available in Micro8, SOIC−8, and DFN−8. The quad channel NCS4325 is available in SOIC−14.
