E-TDA7570

TDA7570 250W PWM high efficiency power audio amplifier Features ■ Output power 2 x 70W / 1 x 250W @ THD10k) connected to a supply voltage referred to the receiver device (as example, a P). Max 10V. ● MUTE - To have a soft mute-play and play-mute transition, an R-C network can be applied (as example 47k, 1F) ● ST-BY - To avoid pop noise due to multiple ST-BY parasitic pulses, an R-C network can be added (as example 47k, 0.1F) ● +Vs-low - This pin supply the low voltage circuits. It can be connected to the +Vs or to a reference voltage comprising between 12V to +Vs. 13/17 Functions, pins and components description TDA7570 A connection to +Vs through a 100 resistor, together a 1F capacitor placed from +Vs-low and GND is possible too. ● 14/17 NL+, INL-, INR+, INR- Input pins. The sign is referred to the input of the differential-tosingleended amplifier. Because the power stage is an inverting stage, the output of the amplifier is with opposite sign with respect these pins. For bridge operation, the connection INL+ must be shorted to the INR- and the connection INL- must be shorted to INR+ TDA7570 Package informations In order to meet environmental requirements, ST offers these devices in ECOPACK® packages. These packages have a Lead-free second level interconnect. The category of second level interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com. Figure 5.
