Description

The TDA7570 is a switchmode 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.
