  • Page 8: Application Information

    Philips Semiconductors Product specification 2 x 6 W hi-fi audio power amplifier TDA1521A APPLICATION INFORMATION Input mute circuit The input mute circuit operates only during switching on and off of the supply voltage. The circuit compares the supply voltage (at pin 3) with an internally fixed reference voltage (V ), derived directly from the supply voltage.
