Philips Semiconductors TDA8559T

Low-voltage stereo headphone ampliﬁer

[1] The supply voltage range at pin VP1 is from 1.9 V to 18 V. Pin VP2 is used for the voltage range from 6 V 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.

13. Application information

13.1 General

For applications with a maximum supply voltage of 6 V (input mode low) the input pins

need a DC path to ground (see Figure 3 and Figure 4). For applications with supply

voltages in the range from 6 V to 18 V (input mode HIGH) the input DC level is

0.5VP+ 0.6 V. In this situation the input conﬁgurations illustrated in Figure 5 and Figure 6

have to be used.
