AD7988-1 Operating Currents vs. Supply (figure 23 in datasheet Rev A)

Question On the AD7988-1 datasheet Rev A, on page 12 of 24, what sample rate is figure 23 "Operating Currents vs. Supply" based on? Answer The max sample rate is 100kSPS. Figure 23 can apply to this sample rate, and any sample rate less than this. The operating current is based on max sample rate 100KSPS.

AD7988-x: ADC input exceed Vref or GND

Question Can the ADC inputs of AD7988-1 or AD7988-5 exceed the reference voltage or go below ground? Answer The ADC inputs should not exceed the reference or go below ground by more than 0.3V as this may result in the ADC being damaged. If this is a common condition, then schottky diodes should be used to protect the inputs and limit them to <0.3V.

For pseudo-differential input applications of the AD7988-1, or AD7988-5, can the IN- be connected to a voltage other than GND?

Q For pseudo-differential input applications of the AD7988-1, or AD7988-5, can the IN- be connected to a voltage other than GND? A The IN- can be connected to max input voltage of -0.1V to +0.1V.
