Description
The TDA7571 i is a fully digital switchmode power
audio amplifier with I2S digital input and PWM
output.
HiQUAD-64
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.
