From the pin description table in the AD7609 data sheet:
V1- to V8- pin description: "The signal on this pin should be 180° out of phase with the corresponding Vx+ pin"
Does it mean that if the positive input is for example +2.5V, the negative should be -2.5V?
Can I connect the negative input to GND while the positive is connected to the measured voltage (like in single ended)?
Another question, which is somehow related to the first one:
The analog input range of this device is +/-10V, +/-5V. How can it be 40V p-p?
I understand the when the Vx+ is +10V and the Vx- is -10V we get +20V and when the voltage is reversed we will get -20V.
But still, it is very confusing... I expected that voltage range of differentioal +/-10V inputs will be 20V...
