(1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
(2) The maximum power dissipation is a function of T_J(MAX), θ_JA and 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 package soldered directly into a 2 layer PC board with zero air flow.
7.5 Electrical Characteristics: ±5 V⁽¹⁾
Single-ended in differential out, T_A = 25°C, V_S = ±5 V, V_CM = 0 V, R_F = R_G = 365 Ω, R_L = 500 Ω; unless specified.

(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that T_J = T_A.
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using
Statistical Quality Control (SQC) methods.
(3) Typical numbers are the most likely parametric norm.
(4) Slew Rate is the average of the rising and falling edges.
(5) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
(6) Negative input current implies current flowing out of the device.
