Operational Amplifier, Precision, Zero-Drift, 50 mV Offset, 0.25 mV/5C, 35 mA
NCS325, NCS2325, NCS4325
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 and SOIC−8. The quad channel NCS4325 is available in SOIC−14.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. Input terminals are diode−clamped to the power−supply rails. Input signals that can swing more than 0.3 V beyond the supply rails should
be current limited to 10 mA or less 2. Short−circuit to ground. 3. This device series incorporates ESD protection and is tested by the following methods:
ESD Human Body Model tested per AEC−Q100−002 (JEDEC standard: JESD22−A114) ESD Machine Model tested per AEC−Q100−003 (JEDEC standard: JESD22−A115) 4. Latch−up Current tested per JEDEC standard: JESD78.
