The NCS333ASN2T1G is a precision op amp with very low input offset voltage (10 µV max) and near−zero drift over time and temperature. This high precision, low quiescent current amplifiers has high impedance inputs with a common−mode range 100 mV beyond the rails as well as rail−to−rail output swing within 50 mV of the rails. The NCS333ASN2T1G features a wide supply range from 1.8 V to 5.5 V (±0.9 V to ±2.75 V for dual supplies). The NCS333ASN2T1G family exhibits outstandingCMRR without the crossover associated with traditional complementary input stages. This design results in superior performance for driving analog−to−digital converters (ADCs) without degradation of differential linearity. The NCS333ASN2T1G is available in compact SC70−5 and SOT23−5 packages and are specified for operation from −40°C to +105°C. The NCV333 is the automotive qualified version available in SOT23−5 and specified for operation from −40°C to +125°C.
