† All characteristics are under open-loop conditions unless otherwise noted. Full range for TA is 0°C to 70°C for TL322C and −40°C to 85°C for

TL322I.

‡ The VICR limits are directly linked volt-for-volt to supply voltage; the positive limit is 2 V less than VCC+.

§ Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.
