Description
The TDA7570 is a switchmode power audio
amplifier with differential inputs and PWM output.
HiQUAD64
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.
