8 / 11 page July 1994 8 Philips Semiconductors Product specification 24 W BTL or 2 x 12 watt stereo car radio power amplifier TDA1518BQ Notes to the characteristics 1. All characteristics, for stereo application are measured using the circuit shown in Fig.3. 2. The circuit is d.c. adjusted at VP = 6 V to 18 V and a.c. operating at VP = 8,1 V to 18 V. 3. Value to be fixed. 4. At 18 V < VP < 30 V the d.c. output voltage ≤ VP/2. 5. Output power is measured directly at the output pins of the lC. 6. With bootstrap and a 100 k Ω resistor from pin 12 to the positive supply voltage (V P), value of bootstrap capacitor is 47 µF. 7. Frequency response externally fixed. 8. Ripple rejection measured at the output with a source impedance of 0 Ω (maximum ripple amplitude of 2 V) and a frequency between 1 kHz and 10 kHz. 9. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz. 10. Noise output voltage independent of RS (VI = 0 V). 11. All characteristics, for BTL application are measured using the circuit shown in Fig.4.
