Hello
I hope you can excuse me because I do not communicate in English.
The operation is confirmed with the circuit shown in Fig. 1.
The input of the oscillator (V3) is turned off, but the voltage of Vout is a sine wave of 6 Vp-p (142 kHz) and INJ (pin 13) is 4.6 V p-p.
If no voltage is applied to IGND-SENSE, why output a signal to IGND-INJ?

Note
Vdd=12V
IGND-SENSE=5mVp-p_60Hz(external noise)
