REVISION 3.0
TDA7575PD
It is recommended to minimize the impedance on the board between OUT2 and the load in order to minimize
THD distortion. It is also recommended to control the maximum mismatch impedance between VCC pins
(PIN21/PIN22 respect to PIN33/PIN34) and between PWGND pins (PIN24/PIN25 respect to PIN30/PIN31),
mismatch that must not exceed a value of 20 mOhm.
With 1OHM feature settled the active input is IN2 (PIN17 and PIN18), therefore IN1 pins should be let floating.
It is possible to set the load capability acting on 1OHM pin as follows:
1OHM PIN (PIN15) < 1.5V: two channels mode (for a minimum load of 2 OHM)
1OHM PIN (PIN15) > 2.5V: one channel mode (for 1 OHM load).
IT IS TO REMEMBER THAT 1 0HM FUNCTION IS A HARDWARE SELECTION.
Therefore it is recommended to leave 1OHM PIN floating or shorted to GND to set the two channels mode con-
figuration, or to short 1OHM PIN to VCC to set the one channel (1OHM) configuration.

C ENABLED: I
C pin (PIN16) > 2.5V
– STD MODE: Vstby (PIN5) > 3.5V, IB2(D1)=0
– HE MODE: Vstby (PIN5) > 3.5V, IB2(D1)=1
– PLAY MODE: Vmute (pin 4) >3.5V, IB1 (D2) = 1
The amplifier can always be switched off by putting Vstby to 0V, but with I

– HE MODE: Vstby (PIN5) > 7V
– PLAY MODE: Vmute (pin 4) >3.5V
For both STD and HE MODE the play/mute mode can be set acting on Vmute pin.
