7 / 11 page May 1992 7 Philips Semiconductors Product specification 4 x 11 W single-ended or 2 x 22 W power amplifier TDA1554Q 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. Frequency response externally fixed. 4. Ripple rejection measured at the output with a source impedance of 0 Ω (maximum ripple amplitude of 2 V) and a frequency between 100 Hz and 10 kHz. 5. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz. 6. Noise output voltage independent of RS (VI = 0 V). 7. Output power is measured directly at the output pins of the IC.
