Dependence of output voltage
on temperature
Output impedance
Dependence of output voltage (pin 6)
on input voltage (pin 18) (Fig.5):
V18(rms) ≤ 5 µV; I2 = I7 = 0 mA
V18(rms) = 1 mV; I2 = I7 = 0 mA
Slope of output voltage (pin 6)
for input voltage range
V18(rms) ≥ 50 µV to
V18(rms) ≤ 50 mV
Dependence of output voltage (pin 6)
on detuning (Fig.6) at input
voltage V18(rms) = 10 mV:
detuning ≤ ± 45 kHz
detuning = for V6 = 1.8 V
detuning = ± 200 kHz
Slope of output voltage with
detuning = 125 ± 20 kHz at
V18(rms) = 10 mV
