Philips Semiconductors

Preliminary specification

2

× 24 W BTL or 4 × 12 W single-ended car

radio power amplifier

TDA8564Q

Notes

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

2. Frequency response externally fixed.

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

Ω, maximum ripple amplitude of 2 V (p-p).

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