7.1 Absolute Maximum Ratings

|---|---|---|---|---|
| Supply voltage, VCC+ to VCC– | 33 | V | ||
| Input voltage | –VCC | +VCC | V | |
| Differential input voltage | –4 | +4 | V | |
| Output current(2) | 550 | mA | ||
| Total power dissipation at (or below) +25°C free-air temperature | See Dissipation Ratings Table | |||
| Maximum junction temperature | 150 | °C | ||
| Operating free-air temperature, TA | Commercial | 0 | 70 | °C |
| Industrial | –40 | +85 | °C | |
| Storage temperature, Tstg | Commercial | –65 | +125 | °C |
| Industrial | –65 | +125 | °C | |
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The THS3122 and THS3125 may incorporate a PowerPAD on the underside of the chip. This pad acts as a heatsink and must be connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction temperature which could permanently damage the device. See TI Technical Brief SLMA002 for more information about utilizing the PowerPAD thermally-enhanced package.
7.2 Dissipation Ratings Table
| PACKAGE | θJA | TA = +25°C POWER RATING |
|---|---|---|
| D-8 | 95°C/W(1) | 1.32 W |
| DDA | 67°C/W | 1.87 W |
| D-14 | 66.6°C/W(1) | 1.88 W |
