... TDA7375V 3 DESCRIPTION The TDA7375V is a new technology class AB car radio amplifier able to work either in DUAL BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with extremely reduced component count. ...

... Silent Turn On/Off and Muting/Stand-by Function The stand-by can be easily activated by means of a CMOS level applied to pin 7 through a RC filter. Under stand-by condition the device is turned off completely (supply current = 1μA typ.; output attenuation = 80dB min.). Every ON/OFF operation is virtually pop free. Furthemore, at turn-on the device stays in muting condition for a time determined by the value assigned to the SVR capacitor ...

... ON/OFF transitions - in combination with a capacitor - for output pop prevention. In any case, a capacitor of at least 100nF from pin 7 to S-GND, with no resistance in between, is necessary to ensure correct turn-on. ...

... TDA7375V vice itself and for the loudspeaker. This particular kind of protection acts in a way to avoid that the device is turned on (by ST-BY) when a resistive path (less than 16 ohms) is present between the output and GND. As the involved circuitry is nor- mally disabled when a current higher than 5mA is flowing into the ST-BY pin important, in order not to disable it, to have the external current source driving the ST-BY pin limited to 5mA ...

... This could be done by taking into account the different timing of the diagnostic output during each case. Normally the clip detector signalling produces a low level at pin 10 that is shorter than that present under faulty conditions; based on this assumption an interface circuitry to differentiate the information is repre- sented in the schematic of fig ...

... SVR CAPACITOR (pin 6): on S-GND and to be placed as close as possible to the device. INPUT SIGNAL GROUND (from active/passive signal processor stages): on S-GND. SUPPLY FILTERING CAPACITORS (pins 3,13): on P-GND. The (-) terminal of the electrolytic capacitor has to be directly tied to the battery (-) line and this should represent the starting point for all the ground paths. 12/15 ...

... In order to meet environmental requirements, ST (also) offers these devices in ECOPACK® packages. ECOPACK® packages are lead-free. The category of second Level Interconnect is marked on the pack- age and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings re- lated to soldering conditions are also marked on the inner box label. ...
