Description

The TDA7571 i is a fully digital switchmode power

audio amplifier with I2S digital input 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.
