MC33272A/74A, NCV33272A/74A, High Slew Rate, Low Input Offset Voltage, Operational Amplifiers, ON Semiconductor The ON Semiconductor MC33272A/74A, NCV33272A/74A Dual and Quad Op Amps incorporate Bipolar inputs along with a patented Zip-R-Trim element for input offset voltage reduction. They have low input offset voltage and high gain bandwidth product. Dual-doublet frequency compensation is used to increase the slew rate while maintaining low input noise characteristics. Their all NPN output stage exhibits no deadband crossover distortion, large output voltage swing, and an excellent phase and gain margin. It also provides a low open loop high frequency output impedance with symmetrical source and sink AC frequency performance.
