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