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
