Oscillator with precise amplitude

Category: Hardware


I want to produce a 100 kHz sine wave with a precision of 1 mV for a peak-peak of 1V.

I found the following application note :

I simulated it but the amplitude of the ouput is always 5V (rail of the LT1632). The max is saturated so the distorsion is huge.

Even when I change the oscillator for a simple signal, the amplitude is not the expected one.

Any idea of this problem ?

Thank you
