TDA7570:Single or dual PWM BTL output

The TDA7570 is a switch mode power audio amplifier with differential inputs and PWM output.

The maximum output current and voltage swing are depending by the output circuitry (power supply, external power transistors and sensing resistors). The device can work as a stereo single-ended channels or a mono bridge power amplifier.
