LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 60134).

Notes

1. When operating at VP > 16 V, the output power must be limited to 85 W at THD = 10% (or minimum load is 6 Ω).

2. Tj is a theoretical temperature which is based on a simplified representation of the thermal behaviour of the device.

Tj =Tc +P × Rth(j-c), where Rth(j-c) is a fixed value to be used for the calculation of Tj. The rating for Tj limits the

allowable combinations of power dissipation P and case temperature Tc (in accordance with IEC 60747-1).
