Philips Semiconductors Preliminary specification
2×23 W high efficiency car radio power
amplifier TDA1561Q
AC CHARACTERISTICS
VP= 14.4V; RL=4Ω; C11= 1000 µF; f = 1kHz; Tamb =25°C; measured in Fig.6; unless otherwise specified.
Notes
1. The distortion is measured with a bandwidth of 10 Hzto 30 kHz.
2. Frequency response externally fixed (input capacitors determine low frequency roll-off).
3. The SE to BTL switch voltage level depends on VP.
4. Noise output voltage measured with a bandwidth of 20 Hzto 20 kHz.
5. Noise output voltage is independent of Rs (see Fig.6)(Vi= 0 V).
