10 Power Supply Recommendations
The THS7530-Q1 device is principally intended to operate with a nominal single-supply voltage of 5 V. Supply
voltage tolerances of ±10% are supported. The absolute maximum supply is 5.5 V.
Supply decoupling is required, as described in Application and Implementation.
Split (or bipolar) supplies can be used with the THS7530-Q1 device, as long as the total value across the device
remains less than 5.5 V (absolute maximum).
