TDA8596
I²C-bus controlled 4 × 45 W power amplifier with symmetrical inputs
I Independently programmable gain (26 dB and 16 dB) of front (channel 1 and channel
3) and rear (channel 2 and channel 4) channels
I Flexible programmable diagnostic levels:
N Programmable clip detect: 2 %, 5 % or 10 %
N Programmable thermal pre-warning
I Selectable information on the DIAG or STB pin:
N The STB pin can be programmed/multiplexed with second clip detection
N Clip information of each channel separately can be directed to the DIAG pin or the
STB pin
N Independent enabling of thermal-, clip- or load fault (short across the load, to V_P or
to ground) available on the DIAG pin
I Offset detection
