They are designed to operate from a single supply over a range of voltages from 5 V to 30 V. Operation from split supplies is also possible provided the difference between the two supplies is 5 V to 30 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 per amplifier are typically less than one-half those of the uA741. AVAILABLE OPTIONS PACKAGE TA The TL322C is characterized for operation from 0°C to 70°C. The TL322I is characterized for operation from – 40°C to 85°C.
