Power Dissipation

The LT1355/LT1356 combine high speed and large output

drive in small packages. Because of the wide supply

voltage range, it is possible to exceed the maximum

junction temperature under certain conditions. Maximum

junction temperature (TJ) is calculated from the ambient

temperature (TA) and power dissipation (PD) as follows:

LT1355CN8: TJ = TA + (PD x 130°C/W)

LT1355CS8: TJ = TA + (PD x 190°C/W)

LT1356CN:

TJ = TA + (PD x 110°C/W)

LT1356CS:

TJ = TA + (PD x 150°C/W)

Worst case power dissipation occurs at the maximum

supply current and when the output voltage is at 1/2 of

either supply voltage (or the maximum swing if less than

1/2 supply voltage). For each amplifier PDMAX is:

PDMAX = (V+ – V–)(ISMAX) + (V+/2)2/RL

Example: LT1356 in S16 at 70

°C, VS = ±15V, RL = 1k

PDMAX = (30V)(1.45mA) + (7.5V)2/1kW = 99.8mW

TJMAX = 70°C + (4 × 99.8mW)(150°C/W) = 130°C
