Philips Semiconductors Product specification
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

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).
