Philips Semiconductors

Product specification

2 x 22 W or 4 x 11 W single-ended car

radio power amplifier

TDA1558Q

Notes to the characteristics

1. All characteristics are measured using the circuit shown in Fig.4

4. Frequency response externally fixed.

5. Ripple rejection measured at the output with a source-impedance of 0

Ω (max. ripple amplitude of 2 V) and a

frequency between 100 Hz and 10 kHz.

6. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.

8. Output power is measured directly at the output pins of the IC.
