The LMV7219 can operate off a single supply or with dual supplies as long as the input CM voltage range (V_CM) has the required headroom to the positive rail V+. The input range extends to slightly below V- voltage. Supplies should be decoupled with low inductance, often ceramic, capacitors to ground less than 0.5 inches from the device pins. The use of ground plane is recommended, and as in most high speed devices, it is advisable to remove ground plane close to device sensitive pins such as the inputs.
