Overview
The NCS2325DR2G is a precision, dual-channel operational amplifier manufactured by onsemi. This device is part of the NCS325, NCS2325, and NCS4325 family, which are known for their zero-drift architecture. This architecture provides continuous auto-calibration, resulting in very low offset voltage, near-zero drift over time and temperature, and flat 1/f noise. The NCS2325DR2G is optimized for low-voltage operation, supporting supply voltages from 1.8 V to 5.5 V, and features rail-to-rail input and output performance, making it ideal for precision DC applications.
