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. Tjis a theoretical temperature which is based on a simplified representation of the thermal behaviour of the device.
Tj=T
c+P×R
th(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).
