1 to 4 W audio power ampliﬁer TDA1015

The TDA1015 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device

is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4 Ωload impedance. The

very low applicable supply voltage of 3,6 V permits 6 V applications.

Special features are:

•single in-line (SIL) construction for easy mounting

•separated preamplifier and power amplifier

•high output power

•thermal protection

•high input impedance

•low current drain

•limited noise behaviour at radio frequencies

RATINGS

Limiting values in accordance with Absolute Maximum System (IEC 134)

HEATSINK DESIGN

Assume VP= 12 V; RL= 4 Ω; Tamb = 45 °C maximum.

The maximum sine-wave dissipation is 1,8 W.

Notes

1. Measured with an ideal coupling capacitor to the speaker load.

2. Measured with a load resistor of 20 kΩ.

3. Measured at Po= 1 W; the frequency response is mainly determined by C1 and C3 for the low frequencies and by

C4 for the high frequencies.

4. Independent of load impedance of preamplifier.

5. Unweighted r.m.s. noise voltage measured at a bandwidth of 60 Hz to 15 kHz (12 dB/octave).

6. Ripple rejection measured with a source impedance between 0 and 2 kΩ(maximum ripple amplitude: 2 V).

7. The tab must be electrically floating or connected to the substrate (pin 9).
