Philips Semiconductors Product specification
24 W BTL or 2 x 12 watt stereo car radio
power amplifier
TDA1516BQ
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 V
P
= 6 V to 18 V and a.c. operating at V
P
= 8,5 to 18 V.
3. At 18 V < V
P
< 30 V the d.c. output voltage ≤ V
P
/2.
4. Output power is measured directly at the output pins of the IC.
5. With bootstrap and a 100 kΩ resistor from pin 12 to the positive supply voltage (V
P
), value of bootstrap capacitor is
47 µF.
6. Frequency response externally fixed.
7. 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.
8. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
9. Noise output voltage independent of R
S
(V
I
= 0 V).
10. All characteristics, for BTL application are measured using the circuit shown in Fig.4.
