Philips Semiconductors Product specification
6 W hi-fi audio power amplifier TDA2614
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.
