where:
⢠PDMAXTOTAL is the sum of the maximum power
dissipation of each amplifier in the package (PDMAX)
⢠PDMAX for each amplifier is calculated in Equation 2:
PDMAX
=
2*VS Ã ISMAX + (VS
-
VOUTMAX
)
Ã
-V----O----U----T----M-----A----X--
RL
(EQ. 2)
where:
⢠TMAX = Maximum ambient temperature
⢠θJA = Thermal resistance of the package
⢠PDMAX = Maximum power dissipation of 1 amplifier
⢠VS = Supply voltage (Magnitude of V+ and V-)
⢠IMAX = Maximum supply current of 1 amplifier
⢠VOUTMAX = Maximum output voltage swing of the
application
⢠RL = Load resistance
