Preliminary data sheet
8.5 Diagnostic input and output
8.6 Differential inputs
In a symmetrical supply the UBP is released when the unbalance of the supply voltage is
within 6 % of its starting value.

Whenever a protection is triggered, except for TF, pin DIAG is activated to LOW level (see
Table
approximately 2.4 V. This internal reference supply can deliver approximately 50 A.
Pin DIAG refers to pin CGND. The diagnostic output signal during different short
conditions is illustrated in
device into Fault mode.
For a high common-mode rejection ratio and a maximum of flexibility in the application,
the audio inputs are fully differential. By connecting the inputs anti-parallel, the phase of
one of the two channels can be inverted, so that the amplifier can operate as a mono BTL
amplifier. The input configuration for a mono BTL application is illustrated in
In SE configuration it is also recommended to connect the two differential inputs in
anti-phase. This has advantages for the current handling of the power supply at low signal
frequencies and minimizes supply pumping (see also
