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

, 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.
