The datasheet of the AD7329 states: "When the AD7329 is in true differential mode, the voltage applied to this (ADCin-) pin is a high voltage signal (±10 V, ±5 V, ±2.5 V, or 0 V to +10 V)."
What 'high voltage signal' is usually tied to the ADCin- pin if I want to use true differential mode?
For VDD and VSS I'm using 15V and -15V respectively. Can I connect ADCin- to either one of these, seeing that this is more than the stated ±10 V?
Or should I step-down the VDD voltage to 10V?
Thanks in advance!
