AC CHARACTERISTICS

VP = 14.4 V; RL =4 Ω; Rs =0 Ω; f = 1 kHz; Tamb =25 °C; measurements in accordance with Fig.9; unless otherwise

speciﬁed.

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; ripple voltage Vripple(max) = 2 V (p-p).

4. Common mode rejection ratio is measured across RL; common mode voltage Vcm(max) = 2 V (p-p).

CMMR (dB) = differential gain (Gv) + common mode attenuation (αcm). Test set-up according to Fig.10; mismatch of

input coupling capacitors excluded.

5. Input signal rejection ratio is measured across RL; input voltage Vi(max) = 2 V (p-p). ISSR (dB) = different gain

(Gv) + mute attenuation (αm).

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.
