The LMH6550 can be used with any combination of positive and negative power supplies as long as the combined supply voltage is between 4.5 V and 12 V. The LMH6550 will provide best performance when the output voltage is set at the mid supply voltage, and when the total supply voltage is between 9 V and 12 V. When selecting a supply voltage that is less than 9 V it is important to consider both the input common-mode voltage range as well as the output voltage range.

Power supply bypassing as shown in Figure 23 and Figure 24 is important and power supply regulation should be within 5% or better when using a supply voltage near the edges of the operating range.
