Preliminary specication
70 W high efciency power amplier
with diagnostic facility
TDA1562Q
AC CHARACTERISTICS
VP = 14.4; RL =4 ; Rs =0 ; f = 1 kHz; Tamb =25 °C; measurements in accordance with Fig.10; unless otherwise
specied.
Notes
1. The low frequency power roll-off is determined by the value of the electrolytic lift capacitors.
2. The low frequency gain roll-off is determined by the value of the input coupling capacitors.
3. Supply voltage ripple rejection is measured across RL; Vripple =Vripple max.=2VPP.
4. Common mode rejection ratio is measured across RL; Vcm =Vcm max.=2VPP. CMMR [dB] = differential gain
(Gv) + common mode attenuation (Ac), (Test setup according Fig. 9; mismatch of input coupling capacitors
excluded).
5. Input signal rejection ratio is measured across RL; Vi =Vi(max) =2VPP. ISSR [dB] = different gain (Gv) + mute
attenuation (Am)
6. Noise output voltage is measured in a bandwidth of 20 Hz to 20 kHz.
7. Noise output voltage is independent of source impedance Rs.
