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.

Notes on the electrical schematic shown in Figure 3
Main characteristics
● 2 channels single-ended or 1 channel bridge PWM amplifier
● Power output: see Table 5
● Gain single-ended = 28 dB
● Gain bridge = 34dB
● Clip detector settled at THD=10%
● Internal master oscillator
The schematic is depicted showing the suggested structure of the printed circuit board
tracks (star points, high current path, components placement).
To avoid malfunctioning due to the parasitic inductance, short connections lengths are
recommended.
