This is a 4×55 watt sound amplifier designed by the popular quad bridge amplifier TDA7560. With a 14.4V supply the circuit gives 4 x 55W output on 2 Ohm load. The circuit is activated when the ST-By and MUTE pins are both connected the Vcc. The maximum supply voltage is 18V. Related Links Circuit More [...]
These chips can deliver 15 Watt RMS per channel, into 4 Ohm loudspeakers. That’s more than enough even for loud home use. The peak power current consumption, when saturating all four channels at the same time, would be 12A, which gives good chances that the computer won’t reset from power supply shutdown in such a [...]
