Product speciﬁcation

2 x 12 W hi-ﬁ audio power ampliﬁer

TDA1521

TDA1521Q

Notes

1. Power bandwidth at Po max −3 dB.

2. Ripple rejection at RS = 0 Ω, f = 100 Hz to 20 kHz; ripple voltage = 200 mV (r.m.s. value) applied to positive or

negative supply rail.

Operating mode: asymmetrical power supply; test circuit as per Fig.13;

VS = 24 V; RL = 8 Ω; Tamb = 25 °C; f = 1 kHz
