(1) The maximum power dissipation is a function of T_J(MAX), θ_JA and the ambient temperature T_A. The maximum allowable power dissipation
at any ambient temperature is P_D = (T_J(MAX) – T_A)/ θ_JA. All numbers apply for packages soldered directly onto a PC Board.

(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. No verification of parametric performance is
indicated in the electrical tables under conditions different than those tested
(2) Negative input current implies current flowing out of the device.
(3) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
(4) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods.
(5) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(6) OIP3 is the third order intermodulation intercept point. In this data sheet OIP3 numbers are single power measurements where OIP3 =
IMD3 / 2 + POUT (per tone). OIP2 is the second order intercept point where OIP2 = IMD2 + POUT (per tone). HD2 is the second order
harmonic distortion and is a single tone measurement. HD3 is the third order harmonic distortion and is a single tone measurement.
Power measurements are made at the amplifier output pins.
