7 / 10 page July 1994 7 Philips Semiconductors Product specification 2 x 22 W BTL stereo car radio power amplifier with loudspeaker protection TDA1553Q AC CHARACTERISTICS VP = 14.4 V; RL = 4 Ω; f = 1 kHz; Tamb = 25 °C; measurements taken using Fig.3; unless otherwise specified Notes to the characteristics 1. The circuit is DC adjusted at VP = 6 V to 18 V and AC operating at VP = 8.5 V to 18 V. 2. At 18 V < VP < 30 V the DC output voltage ≤ VP/2. 3. Conditions: a) V11 = 0 V b) short-circuit to GND c) switch V11 to MUTE or ON condition (rise time ≥ 10 µs). 4. Frequency response externally fixed. 5. Ripple rejection measured at the output with a source impedance of 0 Ω (maximum ripple amplitude of 2 V). 6. Frequency f = 100 Hz. 7. 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 RS (VI = 0 V). PARAMETER CONDITIONS SYMBOL MIN. TYP. MAX.
