• Description: 125mhz Single Supply, Clamping Op Amps
• Manufacturer: Intersil Corporation

package type need to be modified for the EL2150 and
EL2157 to remain in the safe operating area.
The maximum power dissipation allowed in a package is
determined according to [1]:
where:
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
[2]
where:
If we set the two PD
other, and solve for V
various loads and output voltages according to [3]:
Figures 11 and 12 show total single supply voltage V
for various output voltage swings for the SO package. The
curves assume WORST CASE conditions of T
