where:
• P_DMAXTOTAL is the sum of the maximum power dissipation
of each amplifier in the package (PD_MAX)
• PD_MAX for each amplifier can be calculated using

where:
• T_MAX = Maximum ambient temperature
• θ_JA = Thermal resistance of the package
• PD_MAX = Maximum power dissipation of 1 amplifier
• V_S = Total supply voltage
• I_qMAX = Maximum quiescent supply current of 1 amplifier
• V_OUTMAX = Maximum output voltage swing of the
application
R_L = Load resistance
