Notes to the characteristics
1. Full specification of I² C-bus will be supplied on request.
2. Programmable mute state. If the CR3 bit of the mute and port control register is LOW, the mute is active LOW; if it
is HIGH, the mute input is active HIGH.
3. Output current I_O ≈ 1 mA.
4. Unmodulated.
5. f = 400 Hz; R_L = 1 MΩ.
6. 40 Hz ≤ f ≤ 15 kHz.
7. In dual mode: A(B)-signal into B(A)-channel.
In stereo mode: R-signal into left, L-signal = 0, reference is 1 V RMS.
8. Source impedance Z_S < 1 kΩ.
9. Equivalent to an output level of −3 dB at f = 3.183 kHz.
10. V_O = 1 V RMS; f = 1 kHz.
11. Test circuit see Fig.7.
