9 Power Supply Recommendations

The THS4509-Q1 can be used with any combination of positive and negative power supplies as long as the combined supply voltage is between 3 V and 5 V. The THS4509-Q1 will provide best performance when the output voltage is set at the mid supply voltage, and when the total supply voltage is between 3 V and 5 V. Power supply bypassing as shown in Figure 93 and Figure 92 is important and power supply regulation should be within 5% or better when using a supply voltage near the edges of the operating range.
