TDA8594

I2C-bus controlled 4

× 50 W power ampliﬁer

I Fully programmable diagnostic levels can be set:

N Programmable clip detection: 2 %, 5 % or 10 %

N Programmable thermal pre-warning

I Selectable information on the DIAG and STB pins:

N The STB pin can be programmed/multiplexed with second clip detection

N Clip information of each channel can be directed separately to the DIAG pin or the

STB pin

N Independent enabling of thermal, clip or load fault detection (short across or to VP

or to ground) on DIAG pin
