Where:
TJMAX = Maximum junction temperature = +125°C
TAMAX = Maximum ambient temperature = +85°C
θJA = Thermal resistance of the package
The maximum power dissipation actually produced by an IC
is the total quiescent supply current times the total power
supply voltage, plus the power in the IC due to the load, or:
Where:
VS = Supply voltage = 5V
ISMAX = Maximum quiescent supply current = 700mA
VOUT = Maximum output voltage of the application = 2V
RLOAD = Load resistance tied to ground = 150
n = 1 to 32 channels
The required
θJA to dissipate 4.8W is:
