7.2.1 Design Requirements

The supply voltage must be larger than the input voltage range and output range. For instance, this application scales a signal of ±0.5V to ±1.8 V. Setting the supply at ± 2V is sufficient to accommodate this application. The supplies can power up in any order; however, neither supply can be of opposite polarity relative to ground at any time; otherwise, a large current can flow though the input ESD diodes. To limit current in such an occurrence, TI highly recommends adding a series resistor to the grounded input. Vsup+ must be more positive than Vsup– at all times; otherwise, a large reverse supply current can flow.
