Fig.3 The a.f. output voltage at pin 8 as a function

of the resistance values as shown in Fig.4.

Fig.4 Resistor conditions for curves in Fig.3.

(1) Vo af with de-emphasis at ∆f = ± 50 kHz; fm = 1 kHz;

dtot = 1,5%; 0 dB ≅ 770 mV.

(2) Vi: 0 dB ≅ 200 mV at 60 Ω.

Fig.5 The a.f. output voltage at pin 8 as a function

of the input voltage with SFC 5,5 MA at the

input (see Fig.2).

(1) Vo af with de-emphasis at fm = 1 kHz; 0 dB ≅ 770 mV;

curve a: ∆f = ± 50 kHz; dtot = 3%;

curve b: ∆f = ± 25 kHz; dtot = 1%.

(2) Vi: 0 dB ≅ 200 mV at pin 14.

Fig.6 The a.f. output voltage at pin 8 as a function

of the input voltage with broadband input

(60 Ω).
