Philips Semiconductors

Product specification

2 to 6 W audio power amplifier

TDA1011

Notes

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

2. Measured with a load resistor of 20 k

Ω.

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 k

Ω (maximum ripple amplitude: 2 V).

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