Unused Inputs

If a channel is not used, DO NOT tie the inputs together. Due to the high equivalent bandwidth and low offset voltage, tying the inputs directly together causes high frequency oscillations as the device triggers on it's own internal wideband noise. Instead, the inputs are to be tied to any available voltage that resides within the specified input voltage range and provides a minimum of 50mV differential voltage. For example, one input is grounded and the other input connected to a reference voltage, or even (V+).
