Note 1: Voltage values shown are with respect to network ground terminal. Positive current is defined as current into the
referenced pin.
Note 2: The maX1mum junction temperature of the LM14SS is 150°C. For operating at elevated temperatures the cavity
Dual-In-Line Package (J) must be derated based on a thermal resistance of 85°C/W, junction to ambient.
Note 3: These specifications apply for V+ = +9.0V ± 1%, V- = -9.0V ± 1%, TA = O°C to +75°C unless otherwISe noted. All
typicals are for V+ = 9.0V, V- = -9.0V, and T A = 25°C.
