Functions, pins and components description

TDA7570

14/17

A connection to +Vs through a 100

Ω resistor, together a 1μF capacitor placed from

+Vs-low and GND is possible too.

●

NL+, INL-, INR+, INR- Input pins. The sign is referred to the input of the differential-to-

singleended amplifier. Because the power stage is an inverting stage, the output of the

amplifier is with opposite sign with respect these pins. For bridge operation, the

connection INL+ must be shorted to the INR- and the connection INL- must be shorted

to INR+
