7 / 32 page 1997 Jun 27 7 Philips Semiconductors Product specification Low-voltage stereo headphone amplifier TDA8559 Notes 1. The supply voltage range at pin VP1 is from 1.9 to 18 V. Pin VP2 is used for the voltage range from 6 to 30 V. 2. Measured with low-pass filter 30 kHz. 3. Noise output voltage measured with a bandwidth of 20 Hz to 20 kHz, unweighted. Rs =5kΩ. 4. RMS output voltage in mute is measured with Vi = 200 mV (RMS); f = 1 kHz. 5. DC output offset voltage is measured between the signal output and the 0.5VP output. 6. The ripple rejection is measured with a ripple voltage of 200 mV (RMS) applied to the positive supply rail (Rs =0kΩ). 7. DC output offset voltage is measured between the two signal outputs.
