Hi,
I use a vibration sensor that generates a signal +-3V ( +-3V signal, AGnd). I want connect sensor to the differential ADC converter (V+ V- GND).
Is it possible to connect such a signal without any amplifier?
I have to questions:
1) Can I connect the signal in the following way: +-3V signal to V+ , AGnd to GND, V- "not connect" ?
or
2) Do I have to use a differential amplifier to match the signals? In books he writes about 0-3V signals, and I have + -3V. Schemes in the books say that the signal must be for range 0-3V. I have + -3V. signal
