These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All
voltages are measured with respect to the ground pin, unless otherwise specified
(2) The Electrical Characteristics tables list specifications under the listed Recommended Operating Conditions except as otherwise
modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not
ensured.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) Human body model, applicable std. JESD22-A114C.
(5) Machine model, applicable std. JESD22-A115-A.
(6) The maximum power dissipation must be derated at elevated temperatures and is dictated by T_JMAX, θ_JA, and the ambient temperature,
T_A. The maximum allowable power dissipation is P_DMAX = (T_JMAX - T_A) / θ_JA or the number given in Absolute Maximum Ratings,
whichever is lower. For the LME49610, typical application shown in Figure 27 with |V_EE| = V_CC = 15V, R_L = 32Ω, the total power
dissipation is 1.9W. θ_JA = 20°C/W for the DDPAK/TO-263 package mounted to 16in² (103.2 cm²) 1oz. copper surface heat sink area.
