The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded 2/12 TL084 - TL084A - TL084B ELECTRICAL CHARACTERISTICS VCC = ±15V, Tamb = +25°C (unless otherwise specified) Symbol Parameter Input Offset Voltage (Rs = 50Ω) Tamb = +25°C Vio Tmin ≤ Tamb ≤ Tmax TL084I,M,AC,AI,AM, BC,BI,BM Min.
