NCS325 Datasheet, PDF (1/10 Pages) ON Semiconductor – Zero-Drift Operational Amplifier

NCS325
50 mV Offset, 0.25 mV/5C,
35 mA, Zero-Drift
Operational Amplifier
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 mA (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.
