TDA2616/TDA2616Q
LIMITING VALUES
In accordance with the Absolute maximum System (IEC 134).
Note to the limiting values
1. For asymmetrical power supplies (with the load short-circuited), the maximum unloaded supply voltage is limited to
V
P
= 28 V and with an internal supply resistance of R
S
≥
4
Ω
, the maximum unloaded supply voltage is limited to 32 V
(with the load short-circuited). For symmetrical power supplies the circuit is short-circuit-proof up to V
P
=
±
21 V.
