The MC3303 and the MC3403 are quadruple operational amplifiers similar in performance to the uA741, but with several distinct advantages. They are designed to operate from a single supply over a range of voltages from 3 V to 36 V. Operation from split supplies also is possible, provided the difference between the two supplies is 3 V to 36 V. The common-mode input range includes the negative supply. Output range is from the negative supply to VCC – 1.5 V. Quiescent supply currents are less than one-half those of the uA741. The MC3303 is characterized for operation from –40°C to 85°C, and the MC3403 is characterized for operation from 0°C to 70°C.
