THERMAL INFORMATION
The THS3001 incorporates output-current-limiting protection. Should the output become shorted to ground, the
output current is automatically limited to the value given in the data sheet. While this protects the output against
excessive current, the device internal power dissipation increases due to the high current and large voltage drop
across the output transistors. Continuous output shorts are not recommended and could damage the device.
Additionally, connection of the amplifier output to one of the supply rails (±VCC) is not recommended. Failure of
the device is possible under this condition and should be avoided. But, the THS3001 does not incorporate
thermal-shutdown protection. Because of this, special attention must be paid to the device's power dissipation or
failure may result.
The thermal coefficient
θJA is approximately 169°C/W for the SOIC 8-pin D package. For a given θJA, the
maximum power dissipation, shown in Figure 55, is calculated by the following formula:
